Partial Fractions Expansion/Examples/Reciprocal of x by x + 1 squared

Example of Partial Fractions Expansion

 * $\dfrac 1 {x \paren {x + 1}^2} = \dfrac 1 x - \dfrac 1 {\paren {x + 1} } - \dfrac 1 {\paren {x + 1}^2}$

Proof
Therefore:


 * $\dfrac 1 {x \paren {x + 1}^2} = \dfrac 1 x - \dfrac 1 {\paren {x + 1} } - \dfrac 1 {\paren {x + 1}^2}$
