can you solve this Q with steps please
10. The differential equation dy/dt = (y + 4)(y - 1) has (a) an unstable equilibrium solution of y = -4 and an asymptotically stable equilibrium solution of y = 1 (b) an unstable equilibrium solution of y = 1 and an asymptotically stable equilibrium solution of y = -4 (c) unstable equilibrium solutions at both y = -4 and y = 1 asymptotically stable equilibrium solutions at both y = -4 and y = 1 (e) semistable equilibrium solutions at both y = -4 and y = 1
