\[ \boxed {50 x \left (x -1\right ) y^{\prime \prime }+25 \left (2 x -1\right ) y^{\prime }-2 y=0} \]

Solution by Maple

Time used: 0.016 (sec). Leaf size: 31

dsolve(50*x*(x-1)*diff(diff(y(x),x),x)+25*(2*x-1)*diff(y(x),x)-2*y(x)=0,y(x), singsol=all)
 

\[ y \left (x \right ) = c_{1} \left (\sqrt {x}+\sqrt {x -1}\right )^{\frac {2}{5}}+\frac {c_{2}}{\left (\sqrt {x}+\sqrt {x -1}\right )^{\frac {2}{5}}} \]

Solution by Mathematica

DSolve[-2*y[x] + 25*(-1 + 2*x)*y'[x] + 50*(-1 + x)*x*y''[x] == 0,y[x],x,IncludeSingularSolutions -> True]
 

\[ y(x)\to c_1 \cosh \left (\frac {2}{5} \log \left (\sqrt {x-1}-\sqrt {x}\right )\right )-i c_2 \sinh \left (\frac {2}{5} \log \left (\sqrt {x-1}-\sqrt {x}\right )\right ) \]
