ax 2 + bx + c = 0. . 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 numerals a, b, and c are coefficients of the equation, and they represent known numbers.

**Calculator** Use. This online **calculator** is a **quadratic** **equation** solver that will solve a second-order polynomial **equation** such as ax 2 + bx + c = 0 for x, where a ≠ 0, using **the quadratic** **formula**. The **calculator** solution will show work using **the quadratic** **formula** to solve the entered **equation** for real and complex roots.

Use the following steps to write the equation of the quadratic function that contains the vertex (0,0) and the point (2,4). 1. Plug in the vertex. 2. Simplify, if necessary. 3. Plug in x & y coordinates of the point given. 4. Solve for "a." 5. Now substitute "a" and the vertex into the vertex form. Our final equation looks like this:
