In algebra, a quadratic equation is any polynomial equation of the second degree with the following form: ax 2 + bx + c = 0 where x is an unknown, a is referred to as the quadratic coefficient, b the linear coefficient, and c the constant. The

Quadratic formula. The quadratic function y = 1 2 x2 − 5 2 x + 2, with roots x = 1 and x = 4. In elementary algebra, the quadratic formula is a formula that provides the solution (s) to a quadratic equation. There are other ways of solving a

A great thankx to This app inc, this app is an absolute lifesaver in college. Very very very nice and helpful app thanks This app now I can solve all math equation. Helpful when you want to improve in math because answers are available for practice.

It teaches you how to do the equations as well, which is amazing, the camera is occasionally glitchy, but the can be fixed with by exiting and re-entering the app, very Easy to use and very fast, but otherwise a must have! This was great for my Algebra 1 class.

Example 1: Find the Solution for x 2 + − 8 x + 5 = 0, where a = 1, b = -8 and c = 5, using the Quadratic Formula. x = − b ± b 2 − 4 a c 2 a. x = − ( − 8) ± ( − 8) 2 − 4 ( 1) ( 5) 2 ( 1) x = 8 ± 64 − 20 2. x = 8 ± 44 2. The discriminant b 2 − 4 a c > 0 so
