🏁 MISSION

Quadratic Equation Roots by freeman_lex -

A quadratic equation is represented as ax2 + bx + c = 0. Your code must return Iterable containing two values: the roots x1, x2, sorted descending. If there's only one real root, both values will be the same. If there are no real roots, the Iterable should contain the string "No real roots".

list(quadratic_roots(1, 0, -1)) == [1, -1]
list(quadratic_roots(1, 2, 1)) == [-1, -1]
list(quadratic_roots(1, 0, 1)) == ["No real roots"]
