Here we will write a program to solve quadratic equation in Python, so first lets understand how to solve a quadratic equation.

The standard form of a quadratic equation is:

ax

^{2}

+ bx + c = 0, where a, b and c are real numbers and a ≠ 0

The value of a, b and c coefficients should be known to solve the quadratic equation, now lets write the program for the same.

Here is the program to solve quadratic equation in C++.

## Program to Solve Quadratic Equation in Python:

# Solve the quadratic equation ax**2 + bx + c = 0 # import complex math module import cmath a = 1 b = 5 c = 6 # To take coefficient input from the users # a = float(input('Enter a: ')) # b = float(input('Enter b: ')) # c = float(input('Enter c: ')) # calculate the discriminant d = (b**2) - (4*a*c) # find two solutions sol1 = (-b-cmath.sqrt(d))/(2*a) sol2 = (-b+cmath.sqrt(d))/(2*a) print('The solution are {0} and {1}'.format(sol1,sol2))

### OUTPUT:

Enter a: 1 Enter b: 5 Enter c: 6 The solutions are (-3+0j) and (-2+0j)

### Explanation:

We have imported the `cmath`

module to perform complex square root. First we calculate the discriminant and then find the two solutions of the quadratic equation.

We can also change the value of *a, b* and *c* to check with various equations.
