Question

Verify whether the following are zeroes of the polynomial, indicated against them.
$p\left(x\right)=2x+1;x=\frac{-1}{2}$

Answer 1

$p\left(x\right)=2x+1;x=\frac{-1}{2}$
$\therefore p\left(\frac{-1}{2}\right)=2\times \left(\frac{-1}{2}\right)+1$
$=-1+1=0$
Yes, $\frac{-1}{2}$ is the zero of the polynomial $p\left(x\right)=2x+1.$
