Answered by Dwaipayan Shikari last updated on 11/Jan/21

$$\frac{1}{2}{\int }_0^{\mathrm{\infty }}{e}^{-3t}{t}^2{e}^{2t}-e^{-3t-2t}{t}^{2}dtsinh2t=\frac{e^{2t}-e^{-2t}}{2}$$$$=\frac{1}{2}{\int }_0^{\mathrm{\infty }}{e}^{-t}{t}^{2}dt-\frac{1}{2}{\int }_0^{\mathrm{\infty }}{e}^{-5t}{t}^{2}dt$$$$=\frac{1}{2}\mathrm{\Gamma }\left(3\right)-\frac{1}{5^3.2}\mathrm{\Gamma }\left(3\right)=\frac{124}{125}$$
