Factorising By The Highest Common Factor

Algebra

• The language of algebra
• Substitution
• Multiplying algebraic terms
• Dividing algebraic terms
• Expanding brackets: the distributive law
• Factorising by finding the highest common factor

Factorising is the reverse process of expansion. To factorise an algebraic expression, first the highest common factor (HCF) of all terms in the expression must be found. Then the reverse of the distributive law is used to write the expression in factorised form.
