The difference of squares is a special factoring case where the quadratic equation is of the form a 2 −b 2. Example: Factorize x 2 − 9 = 0. Solution: x 2 − 9 = 0. This can be factored as: (x + 3) (x − 3) = 0. Steps to Solve Quadratic Equations by Factoring. Follow the steps to solve Quadratic Equations by Factoring
Solve quadratic equations by factorising, using formulae and completing the square. Each method also provides information about the corresponding quadratic graph. Part of Maths Algebra.
This is the easiest method of solving a quadratic equation as long as the binomial or trinomial is easily factorable. Otherwise, we will need other methods such as completing the square or using the quadratic formula.

How to solve a quadratic equation by factoring. Put the quadratic expression on one side of the "equals" sign, with zero on the other side. Factor the quadratic expression into its two linear factors. Set each of these linear factors equal to zero, creating two linear equations. Solve the two linear equations.
The solution of a quadratic equation is the value of x when you set the equation equal to $$ \red {\text {zero}}$$ i.e. When you solve the following general equation: $$\red 0 = ax^2 + bx + c $$. There are many ways to solve quadratic equations.One of the ways is to factor the equation.
Introduction. When a polynomial is set equal to a value (whether an integer or another polynomial), the result is an equation. An equation that can be written in the form \(\ a x^{2}+b x+c=0\) is called a quadratic equation.You can solve a quadratic equation using the rules of algebra, applying factoring techniques where necessary, and by using the Principle of Zero Products.
Doing so gives us this new equation. Now we need to factor the polynomial. Next, we set the factors equal to zero. Solving these linear equations yields… If you would like to view our video on this topic, use the link below. ideo: Solve Quadratic Equations by Factoring.
