Find the values of x for which the expression (frac{(x – 3)(x – 2)}{x^2 + x – 2})
-
A.
1, -2 -
B.
-1, 2 -
C.
2, 3 -
D.
-1. -2 -
E.
-2, -3
Correct Answer: Option A
Explanation
to find the values of x for which the expression is underlined, let x2 + x – 2 = 0
By factorizing, we have (x + 2)(x – 1) = 0
when x + 2 = 0, when x – 1 = 0, x = -2 or x = 1
The two values are -2 and 1
