There are a few rules you need to follow (or you too will suck at maths).

- The term outside the bracket multiplies everything inside individually
- ab means a times b (see
*Algebra – Make Sure You Know The Basics*for the rest of these rules) - A minus outside the bracket reverses all the signs inside when you multiply out the brackets

E.g. 3(a + 2b) = 3a + 6b

E.g. – 2a(3b^{2} + 2c – 3d) = -6ab^{2} – 4ac + 6ad

**But What About Brackets Times Brackets?**

Everything in the second bracket has to be multiplied by everything in the first bracket!

So (x+4)(x+3)

You have to multiply the second bracket by x and by 4.

x (x + 3) + 4 (x + 3)

= x

^{2}+ 3x + 4x + 12= x

^{2}+ 7x + 12Examiners love to throw in a square bracket. Don’t panic just write the bracket out twice and multiply them together.
