Question 1180375
{{{((x^3-4x)/(2x^2+9x-18))((4x^2+36x+72)/(4-2x))}}}


{{{((x(x^2-4))/((2x-3)(x+6)))((4(x+6)(x+3))/(2(2-x)))}}}


{{{((x(x-2)(x+2))/((2x-3)(x+6)))((2(x+6)(x+3))/(2-x)))}}}


{{{((x*cross((x-2))(x+2))/((2x-3)cross((x+6))))(-(2cross((x+6))(x+3))/cross((x-2))))}}}


{{{((x(x+2))/((2x-3)))(-(2(x+3))/1)}}}


{{{(-2x(x+2)(x+3))/(2x-3)}}}
