Zero of the polynomial p(x)


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

(a) $\frac{-2}{5}$

(b) $\frac{-5}{2}$

(c) $\frac{2}{5}$

(d) $\frac{5}{2}$



The zero of the polynomial p(x) can be obtained by putting p(x) = 0.


$\Rightarrow 2 x+5=0$

$\Rightarrow 2 x=-5$

$\Rightarrow x=-\frac{5}{2}$

Hence, the correct answer is option (b).
