Question

Zero is the polynomial p(x) = 2 − 5x is
(a) $\frac{2}{5}$
(b) $\frac{5}{2}$
(c) $\frac{-2}{5}$
(d) $\frac{-5}{2}$

Answer 1

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

Zero of the polynomial p(x) is given by p(x) = 0.
Thus, we have:
$$\begin{gathered} 2-5x=0 \\ \Rightarrow 2=5x \\ \Rightarrow x=\frac{2}{5} \end{gathered}$$
