1. Find the equilibrium solutions
2. Determine the stability of each equilibrium solution by using the phase diagram.
Expert Solution

Step 1: For Question 1:
To find the equilibrium solutions and determine their stability for the given differential equation:
Find the equilibrium solutions: Equilibrium solutions are the values of x for which (dx/dt) = 0. To find them, set (dx/dt) equal to zero and solve for x:
Now, factor out x:
Setting each factor equal to zero:
a)
b)
Solving for x in equation b:
So, the equilibrium solutions are x = 0 and x = 50.
