your friend says that to solve the equation 5x squared + x - 4 = 2 you should start by factoring the left side as (5x - 4)(x + 1) is your friend correct?
its not correct because since its 5x squared thats going to be in a separate parenthesis for example it would look like this [tex](5x^2 +4)- (x) =2[/tex]
