Factorisation

Reverse process of expanding algebraic expressions

First step in any factorisation

Look for common factors

Switch around strategy: (2−a)(2-a)

−(a−2)-(a-2)

Difference of two squares formula

a2−b2=(a+b)(a−b)a^2 - b^2 = (a+b)(a-b)

Identifying difference of two squares (3 criteria)

Two terms, opposite signs, both perfect squares

When to use grouping in pairs

Four terms with no common factor across all

Form of a quadratic trinomial

ax2+bx+cax^2 + bx + c

Sign rule: if cc positive in ax2+bx+cax^2+bx+c

Both factors have same sign

Sum of two cubes formula

x3+y3=(x+y)(x2−xy+y2)x^3 + y^3 = (x+y)(x^2-xy+y^2)

Difference of two cubes formula

x3−y3=(x−y)(x2+xy+y2)x^3 - y^3 = (x-y)(x^2+xy+y^2)
