Algebraic function with brackets times brackets
Test your understanding of algebraic functions with brackets by practicing it! Work through the below exercises to use it in practice.
🎙️
Let's multiply these bracketed terms together
🎙️
To multiply terms in brackets we need to multiply each pair of terms. We can use the acronym foil, for first outer inner last, to remember
🎙️
Let's multiply our first terms, we have 'X' times 'Y'
🎙️
Now our outer terms, that's minus 7 'X'
🎙️
Then our inner terms, which is plus 4 'Y'
🎙️
And our last terms, which is minus 28
