[SOLVED] multiply algebraic fractions

Need help...

x^2-x-6 * x^2-6x
x-6 x^2+2x-15

I know that my LCD is (x-6)(x-3)(x+5)

x^2-6x simplifies to x(x-6)

my problem is x^2-x-6 does it simplify to x(x-1-6)??

Note quite

$x^2-x-6=(x-3)(x+2)$

$\frac{x(x-3)(x+2)(x-6)}{(x-6)(x-3)(x+5)} = \frac{x(x+2)}{(x+5)}$
