Question

Find zero of the polynomial : $p\left(x\right)=\left(x-4\right)\left(x+5\right)$

Answer 1

Zero of polynomial $p\left(x\right)=\left(x-4\right)\left(x+5\right).$

The zero of polynomial can be found by equating to zero.

$\Rightarrow \left(x-4\right)\left(x+5\right)=0$

$\Rightarrow x=4,-5$

Hence, the answer should be $4,-5.$
