I wish I could assist you, but I don't know how to do linear algebra... yet.  I just wanted to say that this is scary stuff.

anonymous · Answer

its not extremely terrible, but I wish i hadn't taken it in the summer at such an accelerated rate.

anonymous · Answer

I kinda had some introduction to it back in algebra, where we used matrices.  But seeing this, it seems far more difficult than what I used to know.

3(8x^2-5)^2 * 16x
Or:
48x (8x^2-5)^2
