Python program to solve quadratic equation
In this example, we are going to see how we can solve a quadratic equation in Python language. Quadratic equation word is made from the Latin term "quadrates" which means square. It is a special type of equation which is in the form of:
ax2+bx+c=0Example :
# import complex math module
import cmath
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: 7
Enter b: 3
Enter c: 8
The solution are (-0.21428571428571427-1.0473484499010843j) and (-0.21428571428571427+1.0473484499010843j)
Enter a: 7
Enter b: 3
Enter c: 8
The solution are (-0.21428571428571427-1.0473484499010843j) and (-0.21428571428571427+1.0473484499010843j)
