Integral problem

Integrate on both sides:

dy = 1/(c*x^2 + 2*b*c*x) * dx

b and c are constants
c is positive

Re: Integral problem

Hi Polybius;

Yes, partial fractions is the way to go, but it doesn't look easy.

Not quite. If b is non-zero,


which is subtly different from soroban's result.

If b = 0, the answer is -1/(cx) + C.
