# Quadratic Equation Calculator

Quadratic comes from the word 'Quad', which means square, because the variable is getting squared. In elementary algebra, a quadratic equation is a polynomial equation of the second degree. It is also called an 'Equation of Degree 2'. The general form is ax^{2} + bx + c = 0, where a, b, and c are numbers, 'x' represents the unknown value and a ≠ 0, if a equals zero then its a linear equation. Find the roots by Solving quadratic equations using this online Quadratic Equation calculator.

#### Formula:

x = (- b ± √ b^{2} - 4 x a x c) / 2 x a

**Where,**
a = Coefficient of x^{2}
b = Coefficient of x
c = Constant

#### Example

**Find the roots by solving quadratic equation : 2x**^{2}-5x+3

x = (-(-5) ± √((-5)^2 - 4 * 2 * 3)) / 2 * 2

= (5 Â± √(25 - 24)) / 4

= (5 Â± √(1)) / 4

= (5 Â± 1) / 4

= (5+1) / 4 , (5 - 1) / 4

= 6/4, 4,4

= 1.5, 1
