Today's class started out with mental math. I got 4.5/5 today. I did not fully factor x^4-y^4. (x^2-y^2)(x^2+y^2) is NOT the correct answer. I should've written (x^2+y^2)(x-y)(x+y). Now I know anyways. I need to learn how to do 1. Factor sum or difference of cubes, 2.Factor a 4-term expression, 3. factor, more than one method (whatever that means), for accelerated math before I can continue.
