- Factorization by grouping the terms
It means that we need to group the terms with common factors before factoring.
The method of factorization by grouping the terms is given below:
(i) A factor can be taken out from each group from the groups of the given expression.
(ii) Factorize each group
(iii) Then take out the factor common to a group formed.
For instance: Factor grouping the expressions: 1 + a + ac + a2c
Solution: 1 + a + ac + a2c
= (1 + a) + (ac + a2c) = (1 + a) + ac (1 + a) = (1 + a) (1 + ac).
