Rewrite the fraction $\frac{10s+10}{s\left(s^2+10s+10\right)}$ in $2$ simpler fractions using partial fraction decomposition
$\frac{10s+10}{s\left(s^2+10s+10\right)}=\frac{A}{s}+\frac{Bs+C}{s^2+10s+10}$
2
Find the values for the unknown coefficients: $A, B, C$. The first step is to multiply both sides of the equation from the previous step by $s\left(s^2+10s+10\right)$
$10s+10=s\left(s^2+10s+10\right)\left(\frac{A}{s}+\frac{Bs+C}{s^2+10s+10}\right)$
3
Multiplying polynomials
$10s+10=\frac{s\left(s^2+10s+10\right)A}{s}+\frac{s\left(s^2+10s+10\right)\left(Bs+C\right)}{s^2+10s+10}$
$10s+10=\left(s^2+10s+10\right)A+s\left(Bs+C\right)$

Assigning values to $s$ we obtain the following system of equations
$\begin{matrix}10=10A&\:\:\:\:\:\:\:(s=0) \\ -90=10A+100B-10C&\:\:\:\:\:\:\:(s=-10) \\ 110=210A+100B+10C&\:\:\:\:\:\:\:(s=10)\end{matrix}$
