The answer is =3/(x-1)^2+5/(x-1)

Explanation:

Let's do the partial fraction decomposition

(5x-2)/(x-1)^2=A/(x-1)^2+B/(x-1)

=(A+B(x-1))/(x-1)^2

The denomintors are the same, so we equalise the nunerators

5x-2=A+B(x-1)

Coefficients of x, 5=B

Let x=1, =>, 3=A

Therefore,

(5x-2)/(x-1)^2=3/(x-1)^2+5/(x-1)
