Now separating variable x on one side and variable y on other side, we have
![]()
Integrating LHS with respect to y and RHS with respect to x
![]()
Adding 2 and subtracting 2, to the numerator of RHS
![]()
Re - writing RHS as
![]()
Using identities:
![]()
and
![]()
Integrating both sides, we have
log(y) = 2x + 2log(x – 1) + c
