Nikolai Garrison · Answer 1

You would do

(3c^2+6c) (3c^2-6c)

since 3c^2 squared becomes 9c^4

and 6c times negative 6c becomes - 36c^2

I just checked over and it would become

3c^2+6c[3c (c-2) ]

Terry Maynard · Answer 2

You take out the biggest factor of 9 and 36 which is 9c^2. The factors both have the c variable in common so you take the least exponent and put it with the gcf.

9c^2 (c^2+4)
