Can some one tell me if I got this right? Not fishing for the real answer if I got it wrong, just need to know if I did it right or need to try again. The book I'm working through for practice only has answers to odd numbered problems.
Factor Completely:
Q. 8a^2 - 2b^2
My Answer: 2(2a + b)(2a - b)
You are absolutely correct, here are the steps:
2(4a^2-b^2)
2((2a)^2 - b^2)
2(2a-b)(2a+b)
This is most likely how you must have been factorised.
