SUMMARY
The Laplace transform of the function f(t)=(t-5)e^{-17(t-5)}u(t-5) is correctly calculated as \frac{e^{-5(s+17)}}{(s+17)^{2}}. However, the user encountered a discrepancy when comparing their result with Wolfram Alpha, which provided a different answer. The confusion arises from the interpretation of the variable "s" in the exponent, which should indeed be "s+17" according to the properties of the Laplace transform.
