Question

Please help! Simplify:
x^2-9/x^2+5x+6

Answer 1

Factor:
Find factors of -9 that add up to 0
Find factors of 6 that add up to 5

Answer 2

x+3/x+2?

Answer 3

very close

x^2-9 = (x+3)(x-3)
x^2+5x+6 = (x+3)(x+2)
the (x+3) cancels leaving
(x-3)/(x+2)

Answer 4

Okay the first one is a perfect square and can be simplified into : (x-3)(x+3)
Next simplify the bottom equqation(FACTOR)
and get (x+3)(x+2)
When you put this togetehr:
(x+3)(x-3)/(x+3)(x+2)
Cancel out (x+3) = 1 which leaves
(x-3)/(x+2)

Answer 5

Thanks guys! :)
