1 answer:
2x + 5 3x + 5 x + 1
--------------- - ----------------- - -------------------
x(x - 3) x (x+3)(x-3) (x +3)(x - 3)
(x + 3) (2x + 5) - (3x + 5) - x ( x + 1)
= ---------------------------------------------------------
x (x+3)(x-3)
2x^2 +6x +5x + 15 -3x - 5 -x^2 - x
= -----------------------------------------------
x (x+3)(x-3)
x^2 + 7x + 10
= --------------------
x (x+3)(x-3)
(x +5)(x+2)
= --------------------
x (x+3)(x-3)
or
(x +5)(x+2)
= --------------------
x^3 - 9
