3x^3-27x^2+60x
(3x^2-27x+60)x ;divide by x
(x^2-9x+20)3x ;divide by three
(x-4)(x-5)3x ;factor square

3x^3-27x^2+60x

3x(x^2-9x+20) -> factor out 3x

3x(x-5)(x-4)-> factor the polynomial or (if you wanna show the work , use the quadratic equation, but i kinda forgot it, been so long since i used it, and factoring just became natural to me)
