Question

How do you factor this? (Algebra 3)

Answer 1

\[16x ^{3}-64x ^{2}\]

Answer 2

hint: common factor will be 16 and x^2

Answer 3

I did that, but there are more steps to just that isn't there?

Answer 4

thats all there is - why don't you write out what you got and we can check if its correct?

Answer 5

think of there GCF, which is 16x2
then think about how you will get 64x^2
SO what do 16x^3 and 64x^2 have in common? x and 4 right!!
so the you basically you get \[16x^2(x-4)\]
Then you can check to see if thats right by using the distributive property!!

Answer 6
