Implement the quadratic_formula() function. The function takes 3 arguments, a, b, and c, and computes the two results of the quadratic formula:
x1=−b+b2−4ac2a
x2=−b−b2−4ac2a
The quadratic_formula() function returns the tuple (x1, x2). Ex: When a = 1, b = -5, and c = 6, quadratic_formula() returns (3, 2).
Code provided in main.py reads a single input line containing values for a, b, and c, separated by spaces. Each input is converted to a float and passed to the quadratic_formula() function.
Ex: If the input is:
2 -3 -77
the output is:
Solutions to 2x^2 + -3x + -77 = 0 x1 = 7 x2 = -5.50
code:
# TODO: Import math module
def quadratic_formula(a, b, c):
# TODO: Compute the quadratic formula results in variables x1 and x2
return (x1, x2)
