EXAMPLES

EXPANDING BRACKETS

1) Expand the following brackets and simplify:

(a) 3(2g + 3h) + 2(4g – h) = 6g + 9h + 8g - 2h= 14g + 7h

(b) 4(v – 3w) - 2(4v – w) = 4v - 12w - 8v + 2w= - 4v - 10w

(c) a(a + 4b) - b(2a – 5b) = + 4ab - 2ab += + 2ab

Draw your brain

What have you learnt?

In your brain, write or draw everything you can remember about expanding single brackets and simplifying. It can be a skill or a reflection,

or something else that might be prominent in your brain.
