ive encountered xdot and x questions before but never one writen in this dx/dt format so i dont know what to do?

given the first order differential equation dx/dt=x2 -3x-10 find the equlibrium points in the x--xdot plane and draw the trajectory in the plane indicate the time directions and discuss the natures of the equlibrium points
1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution

If I tell you that dx/dt and $\dot x$ are just different notation for the same thing, can you do it then?

i can ye lol, is Xdot just distance in relation to time then?

and are you refering to dx/dt=xdot or xdot dot

usually xdotdot is acceleration
and xdot is velocity
so xdot: dx/dt
xdotdot : d2x/dt2
