Question

Find the zero the polynomial, $q\left(x\right)=x+7$

Answer 1

Finding the zero of $q\left(x\right)=x+7$:
Zeroes of Polynomial:- A real number $\text{'}a\text{'}$ is a zero (or root) of the polynomial $p\left(x\right)$, if $p\left(a\right)=0$.

Given equation,

$q\left(x\right)=x+7$

Equating the given equation with 0, we get

$$\begin{gathered} \Rightarrow x+7=0 \\ \Rightarrow x=-7 \end{gathered}$$
Hence, the zero of the given equation is $-7$.
