Classify (if possible) each critical point of the given plane autonomous system as a stable node, a stable spiral point, an unstable spiral point, an unstable node, or a saddle point. (Order your answers from smallest to largest x, then from smallest to largest y.)
x' = x(1 − x2 − 5y2)
y' = y(5 − x2 − 5y2)
