Bifurcation diagrams. No idea what i'm doing...
The differential equation depends on a parameter \(a\in\mathbb{R}\). Find the equilibrium points and determine whether they are source, sink or neither and sketch the bifurcation diagram. \[x'(t)=x^32ax^2+4x\] where \(a\geq 0\)

Best ResponseYou've already chosen the best response.0If I remember correctly, to find the equilibrium points, find the zero's. So factor out an x... \[x(x^22ax+4)=0\]

Best ResponseYou've already chosen the best response.0plug in the equilibrium points for f'. and If f is less than the equilibrium points then it's a source, and sinks if it's greater than equilibrium point.

Best ResponseYou've already chosen the best response.0ok what I am struggling with is how to split it up. like for some values of a there are a different amount of equlibrium points. are there any resources that just explain what is going on? i'm at my wits end with Hirsch, Differential equations. There isn't even a solution manual
