Explanation:
First, let's rewrite the expression as
Rewriting it in this form is what allows us to do FOIL, which stands for Firsts, Outsides, Insides, Lasts. This is the order we'll multiply in:
- Multiply the first terms:
x*x=x^2x⋅x=x2 - Multiply the outside terms:
x*3=3xx⋅3=3x - Multiply the inside terms:
3*x=3x3⋅x=3x - Multiply the last terms:
3*3=93⋅3=9
Now, we have the following:
Which can obviously be simplified to
