**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)The other common mistake is that people forget to multiply

EVERYTHINGin the brackets.

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

Yes, they are the same.

Usually the number is put

in frontof the brackets.

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

Yes,

BEDMASsays to calculate anything inside theBRACKETSfirst.e.g. 3(2x + 3x + 4 + 5) = 3(5x + 9)

Now expand to 15x + 27
