Given R$=8\backslash$Omega $,$C$=55$mF$,$ and L$=6$H in the equation

$($v$\_($s$)($t$)-$v$\_(1)($t$))/($R$)=$Cv$\_(1)^(\text{'})($t$)+(1)/($L$)\backslash$int$\_0^$t v$\_(1)(\backslash$tau $)$d$\backslash$tau

By applying Lapace transform to solve V $1($s$),$ we can have

V$\_(1)($s$)=($Ks$)/($s$^(2)+$As$+$B$)$Vs$($s$)$

What is the value of B $?$
