How do u solve this with factoring method
You factor out an X out of 3x and x^2 so your next step would look like thisX(x-3)Then you set both factors equal to zeroX=0 x-3=0Add three to both sidesX=0 and x=3
You factor out x leaving you with x(x-3)=0. You divide both side by x that leaves you with x-3=0. You solve for x from there by adding three to both sides. The answer is x=3
