This Math quiz will give you plenty of practice.

1.
What is the common factor in the terms x2 -5x?
2
5
-5
x
x is a part of both x2 and 5x
2.
What is the correct answer when you factorize x2 -5x?
x(x - 5)
x(x + 5)
x(x2 - 5)
x(x2 + 5)
The common factor is placed outside the brackets
3.
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
4.
Factorize the following expression into a pair of linear brackets x2 + 8x + 12
(x - 2)(x - 6)
(x - 2)(x + 6)
(x + 2)(x - 6)
(x + 2)(x + 6)
5.

What is the correct answer when you factorize 3x - 9?
3(x - 3)
3(x + 3)
x(3 - 3)
x(3 + 3)
The common factor is placed outside the brackets
