Consider the problem

${\displaystyle \underset{2}{\overset{4}{}}}\frac{x}{(x-1{)}^3}dx$

Using U$-$Substitution, fill in the following information

so $du=dx$

Write your answer to the definite integration

as a reduced fraction $($EXAMPLE $2/5)$

${\displaystyle \underset{2}{\overset{4}{}}}\frac{x}{(x-1{)}^3}dx=$
