Time used: 0.0 (sec). Leaf size: 62

dsolve(4*(t^2-3*t+2)*diff(y(t),t$2)-2*diff(y(t),t)+y(t)=0,y(t), singsol=all)
 

\[ y \left (t \right ) = c_{1} \sqrt {t -1}+\frac {c_{2} \sqrt {t -2}\, \left (t -1\right ) \left (\ln \left (t -\frac {3}{2}+\sqrt {t^{2}-3 t +2}\right ) \sqrt {t^{2}-3 t +2}-2 t +4\right )}{t^{2}-3 t +2} \]
