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

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

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

Always look to find a

common factorfirst. This often makes the factorising easier.

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

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

- Forgetting to change the signs inside the brackets if a negative common factor is taken.
- Leaving a common factor still inside the bracket i.e. Not factorising fully
- If the common factor is exactly the same as a term in the brackets − forgetting to leave a "1" inside the brackets.
