MCQ
The zero of the polynomial $p(x) = ax + b$ is :
- A$\frac{\text{b}}{\text{a}}$
- ✓$\frac{-\text{b}}{\text{a}}$
- C$\frac{\text{a}}{\text{b}}$
- D$\frac{-\text{a}}{\text{b}}$
✓
Answer
Correct option: B.
$\frac{-\text{b}}{\text{a}}$
Given polynomial $p(x) = ax + b$
put $p(x) = 0$
$ax + b = 0$
$ax = -b$
$\text{x} = \frac{-\text{b}}{\text{a}}$
put $p(x) = 0$
$ax + b = 0$
$ax = -b$
$\text{x} = \frac{-\text{b}}{\text{a}}$
