Question

Question 9
Zero of the polynomial p(x) = 2x + 5 is

A) $- \frac{2}{5}$
B) $- \frac{5}{2}$
C) $\frac{2}{5}$
D) $\frac{5}{2}$

Open in App

Solution

The answer is B.
Given, P(x) = 2x + 5
To find zero of the polynomial, put p(x)=0.
$∴ 2 x + 5 = 0$
$\Rightarrow x = - \frac{5}{2}$
Hence, zero of the polynomial p(x) is $\frac{- 5}{2}$ .
