[tex]\int\frac{e^x}{(e^x-2)(e^2x +1)}[/tex] it should be e to the power of 2x

2. Relevant equations

Using substitution u=e^x, and then using partial fractions

3. The attempt at a solution

I have done this problem two separate ways. One with substitution and then partial fractions, and the other with just partial fractions. Both times I end with different coefficient values. I'm not sure if you can use both substitution and then partial fractions...
