**1. What is the most common mistake people make when expanding brackets?**

Most teachers will tell you that students forget to change all of the signs inside the bracket when expanding by a

negativenumber. e.g. -3(x − 2) = -3x +6 (common mistake is to put -3x-6)

**2. Is (x + 2)2 the same as 2(x + 2)?**

Yes, they are the same.

Usually the number is put IN FRONT of the bracket.

**3. Should I simplify expressions INSIDE the brackets first, if I can?**

Yes, BEDMAS says to calculate anything inside the BRACKETS first.

e.g. 3(2x + 3x + 4 + 5) = 3(5x + 9)

Now expand to 15x + 27
