Question

Verify whether the following are zeroes of the polynomial, indicated against them.
$p\left(x\right)=ax+b;x=\frac{-b}{a}$

Answer 1

$p\left(x\right)=ax+b;x=\frac{-b}{a}$
$\therefore p\left(\frac{-b}{a}\right)=a\times \left(\frac{-b}{a}\right)+b$
$=-b+b=0$
Yes, $\frac{-b}{a}$ is the zero of the polynomial $p\left(x\right)=ax+b.$
