Factoring Quadratic Equations
Worksheets
Welcome to the Math Salamanders' Factoring Quadratic Equations Worksheets.
Here you will find a range of worksheets to help you to
learn to factorise a range of different quadratic equations of the form ax2 + bx + c = 0
All the quadratic equation worksheets in this section factorise with integer values inside each bracket.

Definition of a Quadratic Equation
A quadratic equation is an equation involving the square of a number which is the highest power in the equation.
It is usually in the standard form:
ax2 + bx + c = 0
where a, b and c are numbers, and x is an unknown. The variable a cannot be 0 (but b and c can be 0)
Note that the operations can be '+' or '-'.
It is also sometimes called a second degree polynomial equation.
Examples
The following ARE quadratic equations in standard form:
- x2 + 7x + 4 = 0
- z2 - 25 = 0
- 2w2 + 7w = 0
- 2y2 - 28 = 0
- 4a 2 - ½ a + 15 = 0
The following ARE quadratic equations but not yet in standard form:
-
x2 + 6x = 4
- can be rewritten as x2 + 6x - 4 = 0 (which is in standard form)
-
3n2 - 10 = 6n
- can be rewritten as 3n2 - 6n - 10 = 0 (which is in standard form)
The following are NOT quadratic equations:
- x3 + 7x + 4 = 0 (because of the x3)
- 2y - 28 = 0 (because there is no y2 term)
- 4a5 - ½ a + 15 = 0 (because a has been raised to the 5th power)
How to solve a quadratic equation
There are 2 main methods to use when solving a quadratic equation:
1) The factoring method - this is used for paticular cases when the solution involves integers or fractions
2) The formula method - this can be used for any quadratic equation
The worksheets on this page are designed to be solved using the factoring method (though you could use the formula method to solve the equations if you wish).
