Key learning points

  • Like terms share the same letter powers: 3x+5x=8x3x+5x=8x, but 3x+5x23x+5x^2 cannot combine.
  • Expand: a(b+c)=ab+aca(b+c)=ab+ac; watch double negatives.
  • Substitute values only after simplifying when the question allows.

Worked example 1 — Collect like terms

Simplify 3a+5a−2a3a+5a-2a.

Working

6a6a

Add/subtract coefficients.

Worked example 2 — Expand and simplify

Expand 3(x−2)+43(x-2)+4.

Working

3x−23x-2

Distribute, then collect.

Worked example 3 — Factorise

Factorise 6x+96x+9.

Working

3(2x+3)3(2x+3)

Take out the HCF.
