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 factor first. This often makes the factorising easier.
3. Can a letter be a common factor?
Yes any number, variable or combination of the two can be a common factor.
4. Can a letter be a common factor?

5. What is the most common mistake made when factorising?
- 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.
