Question

State whether True or False, if the following are zeros of the polynomial, indicated against them:

$p\left(x\right)=2x+1,x=\frac{1}{2}$.

• A. True
• B. False

Answer 1

The correct option is B False

Given, $p\left(x\right)=2x+1$

On substituting $x=\frac{1}{2}$ in $p\left(x\right)$, we get

$p\left(\frac{1}{2}\right)=2\times \left(\frac{1}{2}\right)+1=1+1=2$

Since $p\left(x\right)\ne 0$ at $x=\frac{1}{2}$

Therefore, $x=\frac{1}{2}$ is not a zero of the polynomial $p\left(x\right)=2x+1$.

Hence the answer if false.
