This is incorrect - you can't split a fraction up like this. In general :
You should be using partial fractions instead. -

Nope you cannot split up the integral on the LHS by splitting its denominator like that

I did have a doubt about that when i did it. So partial fractions are one option. Are there any other options of doing this without multiplying P with 5-P?

You should be using partial fractions for a differential equation like this. -

Ok thanks ill give it a second go and post back solution on this thread.

There are other methods but they go beyond C4 and would make this more complicated than it is.

After going through the whole process again i get:
LN (P (5-P))=T÷3
Is this right?

I realised another mistake and have the right answer now which is LN (P)÷5 - LN (P-5) ÷ 5 = t÷15
