x^2 - 3x -10

How do I do this? Is it asking me to divide?

The answer choices are as following:

A)x + 3/

x - 5

, x ≠ 5

B)x + 3/

x - 5

, x ≠ -2, 5

C)x2 + 5x + 6/

x - 5

, x ≠ 5

D)x2 + 5x + 6/

x - 5

, x ≠ -2, 5

**MathMate**, Tuesday, May 4, 2010 at 9:23pmI suppose the question is to simplify the expression:

(x^2 + 5x +6) / (x^2 - 3x -10)

The numerator and denominator can be factorized and rewritten as:

((x+2)(x+3)) / ((x+2)(x-5))

If x≠-1, then can can cancel the common factor (x+2) and reduce the expression to:

(x+3)/(x-5)

The expression exists if x≠5.

Thus the answer for the simplified expression is

(x+3)/(x-5) where x≠-2,5
