Thank you so much! I'm curious though how you factored after multiplying each numerator by the perspective denominator factor, so when you multiplied 3a-2 by (a+1) and (a-2) by (a-3), how were you able to simplify? Did you multiply first so 3a-2*(a+1) = 3a^2-5a+2 then simplified?
I'm having trouble with how you were able to factor everything and get 2(a-1) in the numerator!!
