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
answer is A. first one
Multiplication and division are inverse operations.
If you start with a number and divide it and multiply it by the same number (not zero), you get the original number back.
