Part $1$: Evaluate the limit

Evaluate the following limit by simplifying the expression $($first answer box$)$ and then evaluating the limit $($second answer box$).$

$\underset{x1}{lim}\frac{x-x^4}{1-x}=\underset{x1}{lim},=$

Hint: Note: In your written solution, you should write the limit statement $\underset{x1}{lim}$ in every step except the last one, where the limit is finally evaluated.
