Examples, solutions, videos, and worksheets to help Grade 7 and Grade 8 students learn how to solve quadratic equations by factoring.

There are four sets of solving equations using factoring worksheets.

- Solve Quadratic Equation by Factoring (use zero product property).
- Solve Quadratic Equation by Factoring (factor & solve, a = 1).
- Solve Quadratic Equation by Factoring (factor & solve, a ≠ 1).
- Solve Quadratic Equation by Factoring (rearrange, factor & solve).

These are the steps to solve a quadratic equation by factoring:

- Write the quadratic equation in the form: ax
^{2}+bx+c=0, where a, b, and c are constants. - Factor the quadratic expression. Look for two binomials whose product gives you the original quadratic expression.
- Set each of the binomial factors equal to zero. This will give you two separate linear equations to solve.
- Solve each linear equation for x. These solutions are the roots or solutions of the quadratic equation.
- Check if the solutions obtained in step 4 satisfy the original quadratic equation.

Example: Solve the quadratic equation x^{2} − 5x = -6.

- Rewrite down the equation as: x
^{2}− 5x + 6 = 0. - Factor the quadratic expression:

x^{2}− 5x + 6 = 0

(x − 2)(x − 3) = 0 - Set each factor equal to zero:

x − 2 = 0 or

x − 3 = 0 - Solve for x
For

x − 2 = 0

x = 2

For

x − 3 = 0

x = 3 - Check solutions: Substitute x = 2 and x = 3 back into the original equation.

2^{2}− 5(2) + 6 = 0 (True)

3^{2}− 5(3) + 6 = 0 (True)

Remember that not all quadratic equations can be easily factored. Some may require more complex factoring methods, or you may need to use the quadratic formula or completing the square to find the solutions.
