Fascinating Fact:

A pizza recipe needs x + 4 tomatoes per pizza. For 3 pizzas, that’s 3(x + 4). Factorising helps scale recipes easily.

In GCSE Maths, factorisation means rewriting expressions into simpler brackets or terms. This technique helps solve equations faster and shows how numbers or variables share common factors.

  • Factor: A number or expression that divides another exactly, leaving no remainder.
  • Common factor: A number or variable shared by all terms in an expression.
  • Expression: A combination of numbers, letters, and symbols showing a mathematical relationship.
What does factorising mean in GCSE Maths?

Factorising means breaking an expression into simpler parts, like turning x² + 4x into x(x + 4). It’s the opposite of expanding brackets.

Why is factorisation useful in algebra?

It simplifies equations, helps find unknown values, and shows how terms relate. It’s a key method for solving quadratic equations and simplifying expressions.

How do I know when to factorise an expression?

Look for terms with a common factor or an expression that can form brackets, such as a difference of squares or a quadratic pattern.
