🎙️

What would this brackete and squared term expand to?

First we can show the square as just the brackets multiplied by themselves

Now we use FOIL, first, outer, inner, last, to multiply each term in the brackets

Each pairing gives us a term in our final result

We can add the two terms that are 4 'X' together to become 8 'X', and we'll have our result
