(Simple computation) Python Question

Question

The formula for computing the discriminant of a quadratic equation ax^2 + bx + c = 0 is b^2 – 4ac.

Write a program that computes the discriminant for the equation 3x^2 + 4x + 5 = 0.

Answer 1

Another way to solve this is through the use of a lambda function:

discrim = lambda a,b,c: b**2 - 4*a*c

discrim(3,4,5)

Answer 2

Here's one way:

def discriminant(a, b, c):

return b*b - 4*a*c

x = discriminant(3,4,5)

print(x)
