Factorising Expressions
因式分解
Description
Factorise algebraic expressions by taking out common factors — identify the highest common factor of all terms and write the expression as a product, e.g., 6x + 9 = 3(2x + 3)
Mastery Evidence
- Identify the highest common factor of all terms in an expression
- Write the factorised form as a product of the HCF and a bracket
- Check factorisation by expanding the brackets back out
Assessment Prompt
Can your child look at an expression like "6x + 9" and rewrite it with the common factor taken out — as "3(2x + 3)"?
