I know the answer, but I need to know how to solve the problem using beginning algebra techniques.

A rectangle has an area of 152 square units. The larger side is three more than twice the size of the smaller side. What is the measure of each side?

x (2x + 3) = 152

One side is 8, the other side is 19. My problem is that I can't explain how to get the answer when you end up with 2xsquared + 3x.
