Can someone tell me how to factor

2a^2b - 16ab + 32b

Should I factor 2b out of it?

• alg 2 -

yes, which give you

2b(a^2 - 8a + 16)
= 2b(a-4)^2

• alg 2 -

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

• alg 2 -

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?
