What is the starting point in every factorisation problem?
AAdding the like terms first
BSquaring each of the terms
CTaking out common factors
DDividing by the first term
Answer & Solution
Correct answer: C. Taking out common factors
1. Factorisation is the reverse of expanding brackets.
2. The taking out of common factors is the starting point in all factorisation problems.
3. Once the common factor is outside, whatever is left may factorise further.
4. A difference of two squares or a trinomial pattern often appears only after this first step.
