You can put this solution on YOUR website!
You can use distributive property, and if you want, also the lattice method for multiplication which is much like ordinary multiplication.

Try this way:

______1__________5x
.
3_____3_________15x
.
-4x___-4x_______-20x^2

The lefthand column and the upper row are the terms of each binomial factor. Add all the other terms and simplify.
3%2B15x%2B%28-4x%29%2B%28-20x%5E2%29
3%2B11x-20x%5E2
or if you prefer,
-20x%5E2%2B11x%2B3
