Today

You will learn to factorise binomials.

Copy and fill in the blanks: 6p - 12q = 6(... - ...)

Copy and fill in the blanks:

6p​2​​+13p=p(...+...)

This is called factorising binomials.

A binomial is an expression with two (bi) terms.

Remember to always put the largest possible number in front of the brackets.

Factorise:

6pq−30p

1. p(6q−30)
2. 6(pq−5p)
3. 2p(3q−15)
4. 6p(q−5)

Factorise: 12x+15xy

Factorise:

−6x​2​​+15x
