So the question is: Solve the initial value problem using the method of Laplace transforms:
y'' + 2y' +10y = g(t)
where g(t) = { 10, 0<=t<=10
{ 20, 10<t<20
{ 0, 20< t
so i got it to Y(s) =
now after this if someone can help me take the inverse laplace transform of Y(s) so i can get y(t) ... btw its urgent my hwk is due today
