\begin{align*} y^{\prime }&=\left (y-1\right )^{2} \end{align*}

With initial conditions

\begin{align*} y \left (0\right )&={\frac {101}{100}} \end{align*}

Solution by Maple

Time used: 0.012 (sec). Leaf size: 13

dsolve([diff(y(x),x)=(y(x)-1)^2,y(0) = 101/100],y(x), singsol=all)
 
\[ y = \frac {x -101}{x -100} \]

Solution by Mathematica

Time used: 0.003 (sec). Leaf size: 14

DSolve[{D[y[x],x]==(y[x]-1)^2,{y[0]==101/100}},y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to \frac {x-101}{x-100} \]
