Simplify x^2-3x-10/x+2

Question

A. x-5; where x≠ -2
B. x-5; where x≠ 5
C. 1/x-2; where x≠ 2
D. x-2

Answer 1

factoring ... [(x - 5) (x + 2)] / (x + 2)

division by zero (when x = -2) is a no-no

Answer 2

Yeah this helps a lot. (Im being sarcastic)

Answer 3

I think it's
A. x-5, where x is not equal to -2
Correct me if I'm wrong. :)
