Example

func example() -> void:
    print(Res.cbrt(27)) # Prints 3
    print(Res.solve_linear(5, -10)) # Prints 2
    print(Res.solve_quadratic(1, 1, -6)) # Prints [-3, 2]
    print(Res.solve_cubic(2, -11, 12, 9)) # Prints [-0.5, 3]
    print(Res.solve_quartic(1, -10, 35, -50, 24)) # Prints [1, 2, 3, 4]

    print(Res.generate_quartic(1, 2, 3, 4)) # Prints [1, -10, 35, -50, 24]
