A quadratic equation is a second-order equation with one variable of the form

y = ax^{2} + bx + c = 0

where x is the variable, a and b are coefficients and c is a constant.

For example, the equation 5x^{2} - 7x + 2 = 0 is a quadratic equation, where a = 5, b = -7 and c = 2.

A quadratic equation may have one or two roots or it may not have any root. The number of roots depends on the sign of the discriminant Δ, which is a mathematical sentence obtained by the equation

∆ = b^{2} - 4ac

Thus,

When the discriminant is positive (Δ > 0) the quadratic equation has two distinct roots:

x_{1} = ** -b - √∆/2a** and x

The joint form of the above formulas is called the quadratic formula, i.e.

x_{1,2} = *-b ∓ √∆**/**2a*

When the discriminant is zero (Δ = 0), the quadratic equation has two equal roots (practically, it has a single root):

x_{1} = x_{2} = *-b**/**2a*

When the discriminant is negative (Δ < 0), the quadratic equation has no real roots because it is impossible to find the square root of a negative number.
