##### What is expanding two brackets?

When we expand brackets in algebra we ‘get rid of’ the brackets by multiplying out.  When we expand two brackets, each term in one bracket gets multiplied by each term in the other bracket.

“ − × − = + ”

“ − × + = − ”

##### How to multiply out two brackets

1. Write FOIL above your working space.
• F   – First term in each bracket
• O  – Outer pair of terms
• I    – Inner pair of terms
• L   – Last term in each bracket
2. Write down the four multiplications.
• Careful here – you have to be sure to include any minus signs!
3. Simplify by collecting like terms (if there are any).
