# Integrate unknown function?

### off-diagonal

1. The problem statement, all variables and given/known data

I've got B as a function of r B[r] B'[r] for derivative B[r] with respect to r and C for constant

2. Relevant equations

$$\mathbf{\frac{\ B'[r]}{\ r B[r]^2}}+\mathbf{\frac{\ (B[r]-1)}{\ r^2 B[r]}}= C$$

solve for B as a function of r

3. The attempt at a solution

I try to separate r from B[r] term and move it to the other side of the equation and then integrate out but I can't separate them since they are couple to each other.
