Quadratic Equation Solver to find the two unknown roots of equation from the 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.


A quadratic equation is an equation of the form ax2 + bx + c = 0, where a, b and c are constants. For example 3x2 + 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 x2 term. The a often referred to coefficient of x2, 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.
