Question

e..Write a program to find the roots of a quadratic equation.

Answer 1

## This is gonna be a really interesting program!

print("Formula for the quadratic Equation is ax² + bx + c = 0") # First I'll print the formula of the quadratic equation.

## Now we'll have to take the values of a, b, c to find the roots of the quadratic equation.

a=float(input("Enter the value of a : "))

b=float(input("Enter the value of b : "))

c=float(input("Enter the value of c : "))

## I'm taking the variable 'disc' for the discriminant.

disc = b**2-(4*a*c) # This will give me the value of the discriminant.

d= disc**0.5 # I took 'd' for the square root of the discriminant. And for the square root I used d raised to the power 0.5

## Now let's put a condition.  

if disc==0:  

   root = -b/(2*a)

   print("Root of the quadrilateral =", round(root, 2))

elif disc>0:

   root1 = (-b+d)/(2*a)

   root2 = (-b-d)/(2*a)

   print("Root 1 =",round(root1, 2), "and Root 2 =", round(root2, 2))

else:

   print("This quadratic equation does not have real roots.")

   ## You can use 'root1=(-b-d)/(2*a)' and 'root2=(-b-d)/(2*a)' for getting a complex value as the the value will be imaginary.

#   root1 = (-b-d)/(2*a)

#   root2 = (-b+d)/(2*a)

#   print("Root 1 =", root1, "and Root 2 =", root2)
