dPdt=kP(1PM)(1mP))
dPdt=kP(1PM)(1mP)

Solve this differential equation using separation of variables. Only separate the equations and integration (not solving for P)
M= carrying capacity (maximum value)
m= threshold value (minimum value)
k= the proportionality constant

Given:
The differential equation is
dpdt=kP(1pm)(1mp)
he given differential euation can be written as,
dpdt=k(MPM(PMP)
dPdt=k(MPm)(pm))
dp(MP)(Pm)=kdtm)
Integrate the above expression.
(dp(MP)(Pm))kmdt1
Now,
1(MP)(Pm)=AMp)+BPm
A(Pm)+B(MP)(Mp)(Pm))
P(AB)+(bmAm)(Mp)(Pm))
Compare both sides
AB=0)
A=B)
And,
BMAm)
A(Mm)=1)
So,
B=1Mm
Substitute the values in eq---1
1Mm)1Mpdp+1Mn1Pmdp=kmdt
1Mm)[(MP)+(pm)]=ktm+c
InpmMp)=(ktm+C)(Mm)
