# Python Program to Find Roots of a Quadratic Equation

A quadratic equation has two roots — two values of x which satisfies the given equation. Although sometimes these two values may turn out to be the same.

## Finding Roots of Quadratic Equation in Python

``````
# Defining Function To Find Roots
def findRoots(a, b, c):
d = (b*b - 4*a*c)**0.5
x1 = (-b + d)/(2*a)
x2 = (-b - d)/(2*a)
print('\nROOTS OF GIVEN QUADRATIC EQUATIONS ARE:')
print('x1: {0}'.format(x1))
print('x2: {0}'.format(x2))

# Input Section
print('Solving ax^2 + bx + c =0')
a = float(input('Enter the value of a: '))
b = float(input('Enter the value of b: '))
c = float(input('Enter the value of c: '))

# Function Call
findRoots(a,b,c)
``````

Output of the above program:

```Run 1:
----------
Solving ax^2 + bx + c =0
Enter the value of a: 1
Enter the value of b: 5
Enter the value of c: 6

ROOTS OF GIVEN QUADRATIC EQUATIONS ARE:
x1: -2.0
x2: -3.0

Run 2:
----------
Solving ax^2 + bx + c =0
Enter the value of a: 1
Enter the value of b: 2
Enter the value of c: 5

ROOTS OF GIVEN QUADRATIC EQUATIONS ARE:
x1: (-0.9999999999999999+2j)
x2: (-1.0000000000000002-2j)
