Algebraic Expansion and Factorisation
Use distributive laws and common factors; check factorisation by expanding it back.
Key ideas
- single/double brackets
- collect like terms
- common factor
- difference of squares introduction
- substitution
Worked example: (x+3)(x+4)=x²+7x+12.
Common trap: Middle terms must be combined correctly.
Key words
expand — multiply out brackets
factorise — write as a product
term — part of expression
coefficient — number multiplying variable
identity — equality true for all permitted values
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 30 attempts on the same browser.
