Python Program to Solve Quadratic Equation

The standard form of a quadratic equation is:

ax2 + bx + c = 0, where
a, b and c are real numbers and
a ≠ 0

The solutions of this quadratic equation is given by:

(-b ± (b ** 2 - 4 * a * c) ** 0.5) / (2 * a)

Source Code

Output

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

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.

You can change the value of a, b and c in the above program and test this program.
