I have a few problems here. I just wanted to know what to do if I can't factor the equation such as (4x^2) -9=0. That up thing is to indicate what power the number is by so its 4x squared. I have MANY. one good explanation will just help me a lot. heres a few more. (7x^2)=18x-11 (10u^3)-(5u^2)=0 (8y^2)-9y+1=0

(p^2)-p-6=0 2x(x-20)=0

Thanks so much
