बहुपद $p(x)=2 x+5$ का शून्यक है

A

$-\frac{2}{5}$

B

$-\frac{5}{2}$

C

$\frac{2}{5}$

D

$\frac{5}{2}$

Solution

Finding a zero of $p(x)$ is the same as solving an equation $P(x)=0$

Now, $p(x)=0 \Rightarrow 2 x+5=0$

Which give us $x=-\frac{5}{2}.$

Therefore, $-\frac{5}{2}$ is the zero of the polynomial.

Hence, $(b)$ is the correct answer.
