ODE degree: 1.
CAS Maple gives this as type [_linear]
\[ \boxed {y^{\prime }-\frac {2 y}{t +1}=t} \]
✓ Solution by Maple
Time used: 0.0 (sec). Leaf size: 21
dsolve(diff(y(t),t)= t+2*y(t)/(1+t),y(t), singsol=all)
\[ y \left (t \right ) = \left (\ln \left (1+t \right )+\frac {1}{1+t}+c_{1} \right ) \left (1+t \right )^{2} \]
✓ Solution by Mathematica
Time used: 0.054 (sec). Leaf size: 23
DSolve[y'[t]==t+2*y[t]/(1+t),y[t],t,IncludeSingularSolutions -> True]
\[ y(t)\to (t+1)^2 \left (\frac {1}{t+1}+\log (t+1)+c_1\right ) \]
