    Were you able to get it to a quadratic form?

    5x^2-20x-5=0 is in the quadratic form, I need to factor 20x?

    Take the left part (left of the equal sign) and add using the LCD of 5x 2x + 3 x+5 ------- = ----- now cross multiply 5x 10 20x + 30 = 5x^2 +25x Consolidate \[5x ^{2}+5x-30=0\] Divide thru by 5 getting \[x ^{2}+x-6=0\] Do you know how to solve the quadratic?
