*Quadratic Equation Solver* is an online tool for algebraic operation programmed to calculate the two roots of the given real or complex coefficient input values a, b and c. Quadratic equations and functions are very important in Business Mathematics which cover a wide range of business concepts including cost, revenue, break-even analysis, supply demand, market equilibrium and so on

### Definition

A **quadratic equation** is an equation of the form ax^{2} + bx + c = 0, where a, b and c are constants. For example 3x^{2} + 2x - 9 = 0 is a quadratic equation with a = 3, b = 2 and c = -9. The constants b and c can have any value including 0. The constant a can have any value except 0. This is to ensure that the equation has an x^{2} term. The a often referred to coefficient of x^{2}, to b as the coefficient of x and to c as the constant term. Usually, a, b and c are known numbers, whilst x represents an unknown quantity which to be find

### Quadratic Formula

The solutions of two Roots of quadratic equation with real or complex coefficients may or may not be distinct, and they may or may not be real and the roots can be derived from the formula
