6. Write a function that takes the coefficients from ax2 + bx + c and returns the solution to the quadratic equation. You may assume that the input will always have real solutions. Use the following header:

def solve_Eq(a, b, c)

(float, float, float) -> float

Returns the x suth that a * x**2 + b * x + c = 0

>>> solve_Eq(2,-8, 6)
