The **Quadratic Equation **calculator returns the real value roots of a second degree polynomial.

**INSTRUCTIONS**: Enter the following:

- (a) This is the coefficient of second order value
- (b) This is the coefficient of the first order value
- (c) This is the constant

**Quadratic Roots (x):** The calculator returns the real value roots. These are the values of x where the graph of the equation crosses the x axis where y is equal to zero.
