Question

The zero of the polynomial p(x) = ax+b is ______.

• A. $\frac{a}{b}$
• B. $-\frac{a}{b}$
• C. $\frac{b}{a}$
• D. $-\frac{b}{a}$

Answer 1

The correct option is D

$-\frac{b}{a}$

For the zero of the polynomial, equate it with zero.

$p\left(x\right)=0$

$⟹ax+b=0$

$⟹ax=-b$

$⟹x=-\frac{b}{a}$

The zero of the polynomial $p\left(x\right)=ax+b$ is $(-\frac{b}{a})$.
