Square of bracketed algebraic terms
Test your understanding of square of bracketed algebraic terms by practicing it! Work through the below exercises to use it in practice.
🎙️
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
