(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

y = ((x)^−1) (e^−x)

3. The attempt at a solution

Solving this out i got

[(x^-1) - (x^-2)] e^-x

however the book is telling me the answer is

−(x^−1 + x^−2)e^−x

wouldnt that give me (-x^−1 - x^−2)e^−x ??

what did i do wrong??
