I 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
