Suppose that the Laplace transform of differential equation

$y^{\text{'}\text{'}}+2y^{\text{'}}+2y=1$

gives $\{\begin{array}{c}(y)=\frac{1}{2S}+\frac{AS+B}{(s+1{)}^2+1}\end{array},$ where $A,B$ are unstants.

Solve the in itital vahe problem:

$y^{\text{'}\text{'}}+2y^{\text{'}}+2y=1$

$y(0)=-3$

$y^{\text{'}}(0)=1$
