'Factorizing' a number means breaking it down into smaller objects, or factors, which when multiplied together give the original. With numbers it's easy but with letters it's a little more complex.

This Math quiz will give you plenty of practice.

1 .
Factorize the following expression into a pair of linear brackets x2 + 7x + 6
(x + 1)(x + 6)
(x - 1)(x + 6)
(x + 1)(x - 6)
(x - 1)(x - 6)
To check each of the answers it is necessary to multiply out the brackets. Remember that each term in each bracket is multiplied by each term in the other bracket
2 .
What is the common factor in the terms 3x - 9?
x
3

3(x - 3)
3(x + 3)
x(3 - 3)
x(3 + 3)
The common factor is placed outside the brackets
4 .
