Python Program to Solve Quadratic Equation

Quadratic equation: ax² + bx + c = 0 where a, b, and c are coefficients of real numbers and a ≠ 0

Quadratic equation formula $$ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} $$

1# import complex math module  
2import cmath  
3a = 10
4b = 5
5c = 20
6
7# calculate the discriminant  
8d = (b**2) - (4*a*c)  
9
10# find two solutions, based on the formula 
11num1 = (-b-cmath.sqrt(d))/(2*a)  
12num2 = (-b+cmath.sqrt(d))/(2*a)  
13print(f'The solution are {num1} and {num2}')

Output:

1The solution are (-0.25-1.3919410907075054j) and (-0.25+1.3919410907075054j)
