Làm tính chia (12x^3y^3 - 3x^2y^3 + 4x^2y^4) : 6x^2y^3

* Hướng dẫn giải

$\begin{array}{l}\left(12{\mathrm{x}}^3{\mathrm{y}}^3-3{\mathrm{x}}^2{\mathrm{y}}^3+4{\mathrm{x}}^2{\mathrm{y}}^4\right):6{\mathrm{x}}^2{\mathrm{y}}^3\\ =\left(12{\mathrm{x}}^3{\mathrm{y}}^3:6{\mathrm{x}}^2{\mathrm{y}}^3\right)-\left(3{\mathrm{x}}^2{\mathrm{y}}^3:6{\mathrm{x}}^2{\mathrm{y}}^3\right)+\left(4{\mathrm{x}}^2{\mathrm{y}}^4:6{\mathrm{x}}^2{\mathrm{y}}^3\right)\\ =2\mathrm{x}-\frac{1}{2}+\frac{2}{3}\mathrm{y}\end{array}$
