Let
![y = t^r \\ \\ y' = rt^{r-1} \\ \\ y'' = r(r-1) t^{r-2}](https://tex.z-dn.net/?f=y%20%3D%20t%5Er%20%5C%5C%20%20%5C%5C%20y%27%20%3D%20rt%5E%7Br-1%7D%20%20%5C%5C%20%20%5C%5C%20y%27%27%20%3D%20r%28r-1%29%20t%5E%7Br-2%7D)
Substitute into differential equation:
![(r^2 -r) t^r - (5r) t^r + (5) t^r = 0](https://tex.z-dn.net/?f=%28r%5E2%20-r%29%20t%5Er%20-%20%285r%29%20t%5Er%20%2B%20%285%29%20t%5Er%20%3D%200)
Factor out t^r and solve for 'r':
The correct answer is <u><em>(2,−1)</em></u>
