Can someone tell me how to factor
2a^2b  16ab + 32b
Should I factor 2b out of it?

I answered this question in your last post.

yes, which give you
2b(a^2  8a + 16)
= 2b(a4)^2

Who wait, but i thought you cant factor using b because ab is a term by itself

alg 2  Ned, Wednesday, January 7, 2009 at 10:45pm
If the b is not part of the exponent, my last response was incorrect.

Well if your talking about the 2a^2b its 2a^2 * b the exponent is only with the a. So does that mean 2b can factor?
