Question

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

• A. $-5$
• B. $5$
• C. $0$
• D. $3$

Answer 1

Answer: (B)

$5$

Here, $p\left(x\right)=x-5$.
In order to find zero of $p\left(x\right)$, we equate $p\left(x\right)$ to 0,
$i.e$ $p\left(x\right)=0$.
$\Rightarrow x-5=0\Rightarrow x=5$.
$\therefore$ 5 is the zero of $p\left(x\right)$.

Therefore, option $B$ is correct.
