Inverse laplace of a quadratic?

In summary, the inverse Laplace transform of a quadratic function is a function that transforms a complex variable in the Laplace domain back to its original time-domain representation. It is found by first transforming the quadratic function into the Laplace domain and then using tables, algebraic manipulation, or partial fraction decomposition. The formula for finding the inverse Laplace transform of a quadratic is (1/s^2 + a^2) / s, and it can be used in various fields of science, such as physics, engineering, and mathematics, particularly in solving differential equations and analyzing systems with complex variables.

Homework Statement


Y(s)=(s^2+s-6)/(s^2-2s+5)



The Attempt at a Solution


I tried splitting up the bottom into the form (s-1)^2+4, but I can't get the top to factor correctly to make that work. I'm not sure where to go from here, since I can't do partial fractions with the top and bottom being the same order. can anyone help me out?

Here's an advice an engineer gave me, lend the book by schaum called lapalce transforms, it's great for what you need, get my drift. (-:
 

FAQ: Inverse laplace of a quadratic?

What is the inverse Laplace transform of a quadratic function?
