So I've got pretty simple stuff for homework that four months ago I could have done in a heartbeat. But now my brain is all fuzzy and I needs help. The sad thing is that this isn't even Trig. We're just reviewing Algebra from last year. :[
(x^a + y^b) (x^a - y^b)
Mahh. Do I make the x^a * x^a into x^2a or x^a^2 which I'm not sure is allowed. I mean, an exponent on an exponent? No.
But er, yeah. If you have ANY idea what I should do in this dilemma, please help me. Thanks! BAI.
