## Elementary and Intermediate Algebra: Concepts & Applications (6th Edition)

We are asked to solve the equation. Thus, we first make sure the equation is set equal to zero and factor as necessary. Next, since there is 0 on one side of the equation, we set all of the factors equal to zero to solve. Doing this, we find: $$3x^2-12x=0 \\ 3x\left(x-4\right)=0 \\ x=0,4$$
