CAS Maple gives this as type [_quadrature]

\[ \boxed {y^{\prime }=\frac {4 x -9}{3 \left (x -3\right )^{\frac {2}{3}}}} \] With initial conditions \begin {align*} [y \left (0\right ) = 0] \end {align*}

Solution by Maple

Time used: 0.0 (sec). Leaf size: 11

dsolve([diff(y(x),x)=1/3*(4*x-9)*(x-3)^(-2/3),y(0) = 0],y(x), singsol=all)
 

\[ y \left (x \right ) = x \left (-3+x \right )^{\frac {1}{3}} \]

Solution by Mathematica

Time used: 0.04 (sec). Leaf size: 14

DSolve[{y'[x]==1/3*(4*x-9)*(x-3)^(-2/3),{y[0]==0}},y[x],x,IncludeSingularSolutions -> True]
 

\[ y(x)\to \sqrt [3]{x-3} x \]
