argh this isn't a polynomial my bad, I think I should look in the previous chapters notes because I forgot all about these. :s
Hey, I came across an odd problem in factoring polynomials on my hw today. I don't remember covering it in class, and when checking the answer in the back of my book, I was wrong, but I'm not sure how, exactly...
problem:
m^4-256
my answer:
(m^2-16)(m^2+16)
books answer:
(m^2+16)(m+4)(m-4)
I don't see how my answer is wrong...if anybody could tell me why it's wrong, I would appreciate the help.
