Python Math: Calculate the discriminant value
9. Quadratic Discriminant Calculator
Write a Python program to calculate the discriminant value.
Note: The discriminant is the name given to the expression that appears under the square root (radical) sign in the quadratic formula.
Sample Solution:
Python Code:
def discriminant():
x_value = float(input('The x value: '))
y_value = float(input('The y value: '))
z_value = float(input('The z value: '))
discriminant = (y_value**2) - (4*x_value*z_value)
if discriminant > 0:
print('Two Solutions. Discriminant value is:', discriminant)
elif discriminant == 0:
print('One Solution. Discriminant value is:', discriminant)
elif discriminant < 0:
print('No Real Solutions. Discriminant value is:', discriminant)
discriminant()
Sample Output:
The x value: 4 The y value: 8 The z value: 2 Two Solutions. Discriminant value is: 32.0
