user: I'm working on a program that's supposed to solve quadratic equations, and I need to test out a function that calculates the roots. Right now, I need to find the roots for the equation 5x^2 - 8x + 2 = 0. I'll use the coefficients 5 for a, -8 for b, and 2 for c. Can we run this through the function to see what the roots are?

Available functions:
name: quadratic_roots
description: Calculates the roots of a quadratic equation.
parameters: type: dict
properties: a: type: integer
description: The first coefficient.
b: type: integer
description: The second coefficient.
c: type: integer
description: The third coefficient.
required: a
b
c

Ground truth function call(s):
quadratic_roots(a=5, b=-8, c=2)
