Quadratic Equation is an equation where there is only one unknown variable but upon solving it, that single variable has two values. As per the standard definition, a quadratic equation is a second-order polynomial equation in a single variable.

It is represented as below:
ax 2 + bx + c = 0


The roots of the quadratic equation are calculated by the formula below:

x1 = {(-b) + (b2-4ac)1/2} / 2a

x2 = {(-b) – (b2-4ac)1/2} / 2a
