Question

If P(2) = 0 for polynomial P(x), then one factor of p(x) is ....
(A) (x + 2) (B) (x - 2) (C) (x2 + 2) (D) (x2 - 2)​

Answer 1

Given :-

• p(2) = 0

To FinD :-

• One factor of p(x) = ?

Solution :-

$p(2) = 0$

Then surely the value of x is 2

$x = 2 \\ \\ x - 2 = 0$

So the option B is correct.

(x - 2) is one factor of polynomial p(x)
