Hi again

subject:first order linear DE

Using variable separable method,

I have no idea on how to start on these 3 problems, please guide me.

a)dy/dx=(2-y)(2+y),y(0)=-1

b)dy/dx=y(y-1),y(0)=2

c)dy/dx=(y-2)(y-4),y(0)=3

are they solve using the same method? so even if y move to other place,it does not change the method of solving?Thanks in advance
