Factors

Factorising expressions is the reverse of multiplying out brackets - you try to put brackets into an expression. You should make sure you can do well in the test bite for multiplying out brackets before you work on this bite.

Factors are whole numbers or terms that divide into another number or term with no remainder.

For example:

• 1, 2, 3, 4, 6 and 12 are factors of 12
• 1, 2, 4, x, 2x and 4x are factors of 4x

Factor pairs are numbers or terms that multiply together to get a certain number or terms.

For example, the factor pairs of 12 are:

• 1 & 12
• 2 & 6
• 3 & 4

You might be asked to factorise a quadratic expression, in order to solve a quadratic equation.
