Question

Completely factor using the idea of GCF.

16x^3-24x^2-36x

Answer 1

First look at the coefficients : 16, -24 and -36. Can you find a common factor?
Next look at the variables: x^3, x^2 and x can you find a common factor?

Answer 2

I got 4 but I'm not sure how to find the variable...

Answer 3

Alright well, look at it this way: x^3=x*x*x
x^2=x*x
and x=x

Answer 4

well don't they all have only 1 x in common?

Answer 5

Exactly :)

Answer 6

So your GCF must be 4x

Answer 7

Oh ok i get it now! thank you!

Answer 8

No prob :)
