Question

Which of the given expressions results in 0 when evaluated at x = 5?

OA. 5x(x – 7)
OB. (x - 3)(x - 5)
Oc. (x + 7)(x - 2)
OD. (x + 5)(x - 8)

Answer 1

B

Explanation:

Look for an expression with (x - 5 ) as this will give zero when x = 5, that is

x - 5 = 5 - 5 = 0

The only expression with a factor of (x - 5 ) is B
