Outline Quadratic Equations Solving Quadratic Equations Applications Quadratic Equations Definition A quadratic equation is an equation that can be written in the form ax 2 + bx + c = 0 where a , b , and c are real number constants and a 6 = 0. We call a the leading coefficient and c the constant term . Example x 2 = 0 is a quadratic equation. 3 x 2 - 5 x + 7 = 0 is a quadratic equation 10 x 2 = 7 x is a quadratic equation. 2 x 3 + 3 x 2 = 0 is not a quadratic equation. 7 x - 1 = 0 is not a quadratic equation.

### 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.

• 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.
