The sum of the roots of the equation $a x^{2}+b|x|+c=0$ is (a) $\frac{-b}{a}$ (b) 0 (c) $\frac{-2 \mathrm{~b}}{\mathrm{a}}$ (d) None of these

So in the given question, we are told that there are two equations, X squared plus X plus B equal to zero, and X squared plus bx plus a equal to zero, and A is not equal to zero is not equal to be in these equations. And we are told that these equations have a common route, right? So if these equations have a common route, then what is the value of A plus B? This is what we need to find over here. So let's assume that let alpha be the common road, right? Alpha beta common group. Then what we can write us alpha square place alpha A plus B equals zero. And we can also write that alpha squared plus press be alpha our alfa B bless A equal to zero. Right? And from this, what we can do is we can subtract the equation, let this be equation one and equation to. Now let's support these equations. Right? So then we will have alpha times A minus B, plus B minus A is equal to zero. Or we can write as far times A minus B is equal to a minus B, or alfa is equal to work. So if the answer is equal to one, then if we substitute the value of alpha in equation number one, what we would have is one plus A. Plus B is equal to zero. So then we can write the value of A plus, being A plus B is then equal to minus one. So this would be the require answer. So I hope you understood the method. Thank you.

Given the quality equation. So check here for this quite a question. Has, how many routes are there? And what kind of groups out there? This portal accessible to negatively that will become zero, That will become zero and this will give one right? So you'll get one equal to one. Similarly, for example negative B. You will get one equal to one actually negative C. You didn't want to go to the one that is quite the equation right? In extra. It has given its acquired the equation. Even if you solve this will require the equation. Acquired the question. You're getting to the root basically at most possible in acquired the equation. It's only possible whenever it is an identity. For example, if we talk about explosives explosive B equals we have expert blood A plus B, X plus A. Now this is an identity here we have for this there are infinite. Uh roots are possible similarly because an identity which we have three roots are possible more than two routes are possible. Therefore, we can go with its own identity for NDTV have in financials are possible. So therefore for this one we go with infinite and that is option deep. Thank you

So it is given that Yeah 41 plus five c. 2.5 plus 63.5 square Plus 74.5 Q percent. I'll call this X to multiply half both sides. A half X is equal to For 7 1/2. Let's face it do into 1/2 square The 63.5 cube the 74 a half power four. This along add one, there is one place X by two is equal to one plus For 70 to have. Let's face it you into half cube The 63.5 power four person on to infinity. Now for a negative integral index, the expansion of one minus expire minus and is given by one place N. C one into X. Let's end past 1 C2 into extra square Less and less to see three in to execute person infinity. And this is applicable for models of access less than one. Now Putin is four and X is half, so there's one minus half. Power minus four will be one plus 41 a half. That's spicy to into half square. Let's go on to infinity. And that is this that means what is this value? The value is one minus half which is half ar minus four. So that means it is one plus six by two is equal to have power minus four Half power -4 is 16. So that means it's Baidu is 15. That means exists 30. So the answer is option eight. So remember for a cubic equation X cubed plus B, X squared plus C expressed zero. The product of the roots is given by minus debate. So the product of the roots is minus D. B. A. So in option A if you can see the proper study The product of the movies 30. So that means the answer for this question is option A. Okay

Hi the roots of this equation not Cnd. Then the routes of exposure plus two C. Plus the explosives. For political people of you are what? So what you can do here we have here let's see if X. Is extra plus X plus B. Little please X. With no that's what you do for X plus C. Right so it's hard to be X plus C. Old spare plus eight X. Policy plus baby. It's not to be expert. Plus we have C. Square plus it'll give to see X. Uh plus 8 62 Z plus A. X. And then we have plus B. Right? And plus people plus we have a seat. So the same as the situation here we had that is expert plus if you C. Plus X. Plus the spear plus A C. Plus B. No the roots of uh this Cnd so the rules of this uh the roots of this are given by having A. That is X plus C. So one door is going to be X plus C. It will do we have seen so one door is coming on to the actual of europe and the second one will be X plus C. Equal to. Now the roots of this second road is deep. They call these from X equals the regulations are required. Also given us zero and the negative city that is coming up to the option B. Thank you
