Question

simplify (3a(a-4/(a-4)^2)*(2a(a+4)/12a^3)

Answer 1

(a^5 (4 + a) (-4 + 16 a - 8 a^2 + a^3))/(2 (-4 + a)^2)

Answer 2

how do i do this

Answer 3

3a(a-4)2a(a+4) / 12a^3 (a-4)^2

First off, might as well write it all as a single fraction so we can see what we are doing...

U can see that there is (a-4) u can cancel.

There are a couple of a's on top and an a^3 (same as aaa) on the bottom...
