A quadratic equation is an equation that could be written as ax2+bx+c= 0 whena0. There are three basic methods for solving quadratic equations: factoring, using the quadratic formula, and completing the square. Factoring To solve a quadratic equation by factoring, ...
Recognize a quadratic equation Use the zero product principle to solve a quadratic equation that can be factored Determine when solutions to quadratic equations can be discardedWhen a polynomial is set equal to a value (whether an integer or another polynomial), the result is an equation. An ...
Section 7.1 reviews the traditional methods for solving quadratic equations. Section 7.2 tries to convince the reader that Loh's method makes sense and then explains howto compute the roots. In Sect. 7.3 the computation is carried out for two quadratic polynomials and a similar computation for a...

It is a simple matter to solve a quadratic equation once the quadratic expression has been factorised. Since the product of the two factors is zero, it follows that one or other of them must equal z…
Examples of How to Solve Quadratic Equations using the Factoring Method Example 1: Solve the quadratic equation below by Factoring Method. I consider this type of problem as a “freebie” because it is already set up for us to find the solutions. Notice that the left side contains factors of...
