Question

Zero of the polynomial $p\left(x\right)=cx+d$ is :

• A. $-d$
• B. $-c$
• C. $\frac{d}{c}$
• D. $-\frac{d}{c}$

Answer 1

The correct option is D $-\frac{d}{c}$

Zeroes of the polynomial is the value of the variable for which the polynomial becomes $0$, i.e. $p\left(x\right)=0$.

Here, $p\left(x\right)=cx+d$.

Putting $p\left(x\right)=0$, we get,

$cx+d=0$

or, $x=\frac{-d}{c}$.

Therefore, option $D$ is correct.
