I have the following differential equation: [itex]x' = f(x) + a[/itex] with [itex]f(x) = (x+1)^{2}.(1-x)[/itex]

Now i have the following questions:

1. Sketch the phaseline for [itex]x' = f(x) + a[/itex] with [itex]a = -2, -1, 0, 1[/itex]

Don't calculate the exact intersections but make a qualitative correct picture.

2. Give the values for a where there are 3 equilibrium points. Hint: What are the maxima and

minima of f.

I really am trying but i don't understand how to solve this question and i really need some help on how to do this one.
