Here is a question from NCERT-Exampler pg-15 question no. 6
For what value of $a$ and $b$, are the zeros of $q(x)=x^3+2x^2+a$ also the zeros of polynomial $px(x)=x^5-x^4-4x^3+3x^2+3x+b$ ? Which zeros of $p(x)$ are not the zeros of $q(x)$?
this querstion's answer is
$a=-1, b=-2$; 1 and 2 are the zeros of $q(x)$but not the zeros of $p(x)$
now how to solve this question...
please help me to short out with this problem and it would be so kind if you show me steps how you have done this and please take this very urgent because tomarrow is my test...
thanks for your answers.
