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

[tex]\int[/tex] 1/(x[tex]^{2}[/tex]+4x+5)[tex]^{2}[/tex]

2. Relevant equations

I am using partial fraction decomposition

3. The attempt at a solution

1/(x[tex]^{2}[/tex]+4x+5)[tex]^{2}[/tex] = Ax+b/(X^2+4x+5) + Cx+D/(x^2+4x+5)^2

1 = (Ax+b)(X^2+4x+5) + Cx+D

When i multiply through to find the values for A and b and c i get zero because there is no X^3 or x^2 or x on the left side. Am i doing something wrong or do i need to use another method to solve this integral?
