Question 200830
[ { x^2-6x +9} / {12-4x} ] * [ { x^6 -9x^4} / {x^3 -3x^2}]
.
[ ( x-3)(x-3) / -4x (x-3) ] * [ ( x^4)(x^2 -9) / (x^2) ( x-3) ]
.
simplify  by  cancelling  like  terms,  num  and  den
.
-x^4 (x^2 -9) / 4 x^2
.
(-1/4) x^2 ( x+3)(x-3)
.
 Check  using  x=2  in  both  original  and  answer,  both  = +5,  ok
