=∫ ((x^2 (x+1)^2 )/((x+1)))dx=∫ x^2 (x+1)dx=(x^4 /4)+(x^3 /3)+C    ⟨M.T⟩
$$=\int\:\frac{{x}^{\mathrm{2}} \left({x}+\mathrm{1}\right)^{\mathrm{2}} }{\left({x}+\mathrm{1}\right)}{dx}=\int\:{x}^{\mathrm{2}} \left({x}+\mathrm{1}\right){dx}=\frac{{x}^{\mathrm{4}} }{\mathrm{4}}+\frac{{x}^{\mathrm{3}} }{\mathrm{3}}+{C} \\ $$$$ \\ $$$$\langle{M}.{T}\rangle \\ $$
