Write a program to calculate the roots of a quadratic equation.

PROGRAM:

# The general equation of a quadratic equation is ax^2+bx+c=0.

a=int(input("Enter \'a\':"))

b=int(input("Enter \'b\':"))

c=int(input("Enter \'c\':"))

n=(b**2)-(4*a*c)

if (n==0):

    print("Real and equal roots.")

    print("The roots of a quadratic equation"+str(a)+"x^2"+str(b)+"x"+str(c)+"is",-b/2*a)

elif (n<0):

    print("Imaginary roots")

elif (n>0):

    print("Real and distinct roots.")

    print("The one  root of a quadratic equation"+str(a)+"x^2+"+str(b)+"x+"+str(c)+"is ",(-b+(n**(1/2)))/2*a)

    print("The another root of a quadratic equation"+str(a)+"x^2+"+str(b)+"x+"+str(c)+"is ",(-b-(n**(1/2)))/2*a)

OUTPUT:

Enter 'a': -6
Enter 'b': 5
Enter 'c': 1

Real and distinct roots.
The one  root of a quadratic equation-6x^2+5x+1is  -6.0
The another root of a quadratic equation-6x^2+5x+1is  36.0
