Hi i have this question, which im pretty sure is done using integration by parts:

$\displaystyle \int (x-1)e^{2x-1}$

and i get this answer:

$\displaystyle \frac{1}{4} e^{2x-1}(2x-3)$

But my book says it should contain $\displaystyle (2x-1)$ instead

Can anyone see where i may have slipped up. If it helps i can post the steps i took?

Thank you
