## A Worked example to illustrate how the quadratic calculator Works:

This quadratic function calculator helps you find the roots of a quadratic equation online. The calculator, helps you finds the roots of a second degree polynomial of the form ax^2+bx+c=0 where a, b, c are constants, a\neq 0. This calculator is automatic, which means that it outputs solution with all steps on demand. Furthermore the calculator is highly accurate and effective. Over 1,000,000 students worldwide are already using EquationCalc.com to learn algebra.

## Polynomial function calculator that works

Our polynomial roots calculator works in the most fundamental way using the famous quadratic formula

x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{ 2a }

The formula maintains that any polynomial of degree two can be solved using the formula where a,b,c are the constants in the equation respectively. With this calculator, it is easy to find the roots of any equation without worries. Simply enter your math in the textarea provided, Hit calculate button to find the solution.

The roots of quadratic equations can either be real, complex or zero. A complex root means that the solution has both the real and an imaginary part of the form a+bi where i^2=-1. On the other hand, a real solution means that the roots are all real numbers

## Solved Quadratic Formula Examples

Quadratic formula calculator with imaginary support

Usually, the roots of an equation are complex if the Discriminant is negative. The Discriminant D= (b^2-4ac). Most online algebra calculators don�t have the capacity for imaginary numbers. However, this calculator supports both real and imaginary roots.

## Discriminant calculator

With this calculator you can calculate the discriminant too. The discriminant is a constant, usually calculated to determine the solvability of a quadratic.

D= (b^2-4ac)

To find the discriminant, just select the �Find Discriminant� Option on the solution panel.
