a)2/5
b)5/2
c)-2/5
d)-5/2​

Answer 1

Answer:

$p(x)= 2 - 5x \\ \\ 2 - 5x = 0 \\ \\ = > - 5x = - 2 \\ \\ ( - \: and \: - \: cancelled) \\ \\ = > 5x = 2 \\ \\ = > x = \frac{2}{5}$

option ( a ) is ✔

hope it helps u

Answer 2

Answer:

2/5

Step-by-step explanation:

Put the value 2/5 in the given equation

We get, p(x) = 2 - 5 * (2/5)

=2 - 2

=0

Hence, 2/5 is the zero of the given polynomial because 0 is the remainder when 2/5 is divided by 2 - 5x
