**1. What is the point of factorising?**

By breaking an expression up into its factors, further tasks such as solving equations and simplifying are made much easier.

**2. What are the common mistakes made when expanding?**

One of the most common mistakes is to forget to multiply

ALLof the terms inside the brackets.e.g. 3(x − 4) is not equal to 3x − 4!

**3. Is (x + 4)3 the same as 3(x + 4)?**

Yes, they are the same.

Usually the number is put

IN FRONTof the bracket.

**4. 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

**5. Can every algebraic expression be factorised?**

No. Many expressions cannot be factorised and many expressions need advanced techniques to factorise them.

**6. What is the FIRST thing to look for when trying to factorise?**

Always look to find a common factor first. This often makes the factorising easier.

**7. Can a letter be a common factor?**

Yes any number, variable or combination of the two can be a common factor.
