The Laplace Transform of the signal x(t) = u(t − 2)(tu(t)) is given by which of the following expressions? [”” represents convolution operator]

\frac{e^{-2s}}{s^2(s-2)}

$\begin{array}{c}\frac{e^{-2(s-2)}}{s^3}\end{array}$

$\begin{array}{c}\frac{s{e}^{-2s}}{{(s-2)}^2}\end{array}$

\frac{e^{-2s}}{s^3}
