MATH 1414 Section 1.4 Quadratic Equations What is a quadratic equation ? It is any equation in the following form where a,b, and c are constant real numbers. Any equation with a highest exponent of 2 (i.e. degree 2) is a quadratic equation and will have to be solved in special ways. In this section we will examine three such ways: 1. Solve by factoring. (Equation must be set to zero.) 2. Solve by taking square roots (only if middle term is missing or expression is a perfect square.) 3. Solve by using the quadratic equation. (Equation must be set to zero.) Factoring By factoring we mean reversing or undoing the F.O.I.L. method for multiplying. We use the zero-product property and so the equation must be set equal to 0. Example 1. Solve by factoring . Example 2. Solve by factoring . Example 3. Solve by factoring . Example 4. Solve by factoring .
Example 5. Solve by factoring

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
