CAS Maple gives this as type [_quadrature]

\[ \boxed {y^{\prime }-y^{2}+4 y=-12} \] With initial conditions \begin {align*} [y \left (0\right ) = 6] \end {align*}

Solution by Maple

Time used: 0.0 (sec). Leaf size: 5

dsolve([diff(y(t),t)=y(t)^2-4*y(t)-12,y(0) = 6],y(t), singsol=all)
 

\[ y \left (t \right ) = 6 \]

Solution by Mathematica

Time used: 0.002 (sec). Leaf size: 6

DSolve[{y'[t]==y[t]^2-4*y[t]-12,{y[0]==6}},y[t],t,IncludeSingularSolutions -> True]
 

\[ y(t)\to 6 \]
