c and d

Use the Laplace transform to solve the following initial value problem:
y" - 6y +9y=0 y(0) = 5, y/(0) = 2
a. Using Y for the Laplace transform of y(t), i.e., Y = L{y(t)}, find the equation you
get by taking the Laplace transform of the differential equation
x(s2²-6s+9)
b. Solve for
Y(s)
-6s+ 9)-5s-2 +30 = 0
=
55 - 28
(s-3)²
c. write the above answer in its partial fraction decomposition, Y(s) =
=
Y(s) = +
d. Now, by inverting the transform, find
y(t) =
.
A
B
+
s+a (s+a)²
