Solve by factoring. $$y(y-5)^{3}-14(y-5)^{2}=0$$

All ready for number 79. We have this uh situation where we're trying to factor these things out. So why minus five Cuban? A y minus five squared? We can actually factor out why minus five squared from each situation, leaving it with a Y. Times y minus five minus 14. Here being set equal to zero. Now in this case since this happens twice, all we have to do is just set it equal to 01 so we'll have y equals five as one of our solutions. And then here what we'll need to do is distribute, we'll have y squared minus five y minus 14 equals zero. And that's gonna buy involve some factoring. So we're going to have why uh factors of 14 or seven and two. So why minus seven? Y plus two? Both equal zero. That's gonna leave us with Y equals a positive seven. And why equaling a negative too?

That's probably getting another quadratic in a standard form, and we're supposed to factor it in order to solve. Um, so if you look at this quickly, um, if you no difference of squares, that's an easy way. And quick wait a factor. It's not the nuclear fact they're using. Yes, the check like we've been doing. So here. Don't start out to buy. Why? Because that's what you know. It has those first few numbers have to multiply it equal for So it's either four and one and two and two. You see 25 all we quickly think, um, 25 is five squares, so we have plus five the modified from the sons of working because these fives cancel out plus 10. What will you foil? This you get plus 10 y minus 10. Watch those to cancel out. So now way have the 2 to 5 plus five equals zero or who are minus five equals zero betweens. When you solve these, why equals negative five halves or positive five. House

To solve the equation. Three y squared, minus 14 line minus five equals zero. So, looking at this, I can see that it is in standard form. Uh, we're starting with the biggest exponents toothy. Next biggest. Export it to the smallest ex moment and the right side of the equation is equal to zero. So that means we can use Ah, the A C method of factoring to factor this polynomial. So we're going to identify or a B and C are a the number one of, I swear, just three r b. The number in front of why is negative 14 and R. C. The number by itself is negative. So we're gonna multiply any and see so three times negative five is going to give us a negative 15. And R B is negative. 14. So we're looking for two numbers that multiply to make negative 15 and those same two numbers have to add up to negative 14. So what stands out to me here looking at this whenever I see that our A c is a number and R B is one number less than that, it always kind of makes me think of the factors one times B A C number. So one times for teeth. If we make her numbers one and 15 then we have to figure out where the negative signs go because we know we're multiplying to a negative number. So that means one of the numbers has to be negative. And since we're adding up to a negative number, that means the bigger number should be negative. So we're gonna make the 15 negative, and we're gonna make sure that the sports So one times negative 15 is negative. 15. So this statement is true and one plus negative 15 is negative. 14. So this is also true, so we know that our two numbers are positive one and negative 15. So now we're going to split the beach here in the middle term into negative 15. Why worse? One. Why? And then we're gonna bring everything else down. So now we're gonna group these 1st 2 germs, and we're gonna group the last two terms, and we're gonna see what we can factor out. And the first grouping, I have three y squared minus 15. Why these air both multiples of three, and they both have a why so I'm gonna factor out. Realize when I do that I get why minus five out of Theseventy grouping, there's nothing I can factor out. So I'm gonna factor out a what? That's not I mean, you're not really factoring anything out, but it's gonna come in handy to write it that way later on. And instead of writing one, why I can just write this as Why? Because it's the same thing. So now looking at this, I can see that I have two terms. My first term is three y times Y minus five. It's being added to my second term, which is one times wine. Satisfy. So both terms have wine, Linus piping them. So what I'm gonna do is I'm actually gonna factor out the wine minus five from both terms. So in my first term, I'm just left with this three. Why? And in my second term, I just have this one that's being had it, and that's why I decided to write the one on the outside so that it would be clear why there's a close one here. So now that this is totally factored, we can use the zero factor property to help us out. You're gonna bring this right over here. We have one minus five times rea y plus one equal zero. So the zero factor property tells us that we have a factor. A surfer swim being multiplied by another factor are others for 2nd 1 and it equals zero. Then we have to do than ah either. The first factor was zero for the second factor was zero or both of number zero. Because the only way to get zero when you're multiplying is she multiplied by zero. So that means maybe there's 1st 1 was zero. We need to find the why that would make this 1st 10 And we also need to find what why would make this second factor zero. So that's where we get these two equations. Now all we have to do is solve both of them for why to figure out what wise would make our recreation true. So in the first equation to solve, I'm just going to add five to both sides. That way this will cancel and I get why equals zero spot, which is five. So that is our first solution for why looking at the second equation. We three were close. One equals zero. So I'm gonna start by subtracting room from both sides. That way this cancels and I get three. Y is equal to zero minus one, which is negative one, don't you get? Why buy it? So right now it's being multiplied by three. So I'm going to divide by three so that this cancels and then I get why equals negative 1/3. So now we have our two solutions for Why? Why equals five and y equals negative 1/3.

Question is asking about the solution of this system of depression. And the first equation is X minus three. Why is it was toe minus type in the second equation is access quiet. Plus why Squire, minus 25 physic was +20 Now from a patient number one we can rewrite. It s X. Is it questo? Three y minus five. Now put this value packs into question. Number toe. Many question to will be three white, minus five Esquire. Plus why Squire minus 25 is it was +20 Now by the simplification, we can be ready. Jays three vice part, which is nine White square, then minus five is quite, which will be plus 25 minus Karbi. What? Bless Why Esquire minus 25. Because 20 now again, by the simplification, weaken very base. Nine wives published by express will be pain vice quiet and minus 31 minus 30. What? Plus 25 minus damned if I will be. +02 is equal to zero. So the question can be y spire minus +31 is equals to zero. Take vitamin from here. Then why minus three will be remaining part, which is equals to zero. So the solution for this the question is, why is Equus 20? Or why is it was three now to find out the respective ill you export? Why? Because 20 iniquity number one then actually will be minus fight. And But why is it close to three, then? Actually, you will be four. Now, this is the complete answer of discretion and bears off the X and y for this question.
