how can write this formula in python?

how can i write a function that takes 2 integer parameters, a and b. Inside the function I need calculate the value of x using the formula below (where the term 2a indicates that 2 is multiplied by a). I'm quite lost with doing this can someone please give me a hint on how to start this code in python?

Here is how:

def x(a, b):
    return (b+(b**2-1)**0.5)/(2*a)

In python, we use ** for power symbols.

You can use the below method to achieve your goal.

# remember to import math
x = lambda a, b: (math.sqrt(b**2 - 1) + b)/(2 * a)

Now you can use this function: 

x(5, 10) # gives 1.99498743710662 (roughly)
