Algebra | Expanding Three Brackets | Maths with Mrs. B

The video tutorial explains how to expand three brackets using a three-step process. Initially, the first two brackets are expanded and simplified, followed by multiplying the result with the third bracket. Finally, like terms are combined to simplify the expression. The tutorial provides three examples using different variables (X, A, Y) to demonstrate the process in detail.

What are the three steps to follow when expanding three brackets?

In step one, what do we do with the first two brackets?

How do we simplify the terms after expanding the first two brackets?

What is the result of combining the like terms X^2 and -5X^2?

What do we obtain after expanding all three brackets in the first example?

What is the result of combining -4Y and 3Y in the last example?

What is the final expression obtained after expanding the last set of brackets?
