Topic: Algebraic Manipulation and Formulae (Higher - Unit 2)

Specification References: N5.1h N5.1h Manipulate algebraic expressions by collecting like terms, by multiplying a single term over a bracket, and by taking out common factors. Multiply two linear expressions

Candidates should be able to:

• understand that the transformation of algebraic expressions obeys and generalises the rules of generalised arithmetic
• manipulate an expression by collecting like terms
• multiply a single term over a bracket
• write expressions using squares and cubes
• factorise algebraic expressions by taking out common factors
• multiply two linear expressions such as and  at Higher tier

Notes

This reference includes all the requirements of N5.1 and some additional requirements for the Higher tier only.

Examples

1. Expand and simplify 3(a – 4) + 2(2a + 5)
