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

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

Answer 1

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