Find the values of x for which the expression \(\frac{(x - 3)(x - 2)}{x^2 + x - 2}\) is undefined?
A
1, -2
B
-1, 2
C
2, 3
D
-1. -2
E
-2, -3
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
to find the values of x for which the expression is undefined, let x\(^2\) + 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
