  1. \text{a) (12}$x^{4}$ $y^{3}+8$ $x^{3}$ $y^{2}-4x$ $y^{2}):2xy$
    \text{=(12}$x^{4}$ $y^{3}:2xy)+(8$ $x^{3}$ $y^{2}:2xy)+(-4x$ $y^{2}:2xy)$
    \text{=6}$x^{3}$ $y^{2}+4$ $x^{2}y-2y$

    \text{b) (4}$x^{5}+6$ $x^{3}-2$ $x^{3}):2$ $x^{2}$
    \text{=(4}$x^{5}:2$ $x^{2})+(6$ $x^{3}:2$ $x^{2})+(-2$ $x^{3}:2$ $x^{2})$
    \text{=2}$x^{3}+3x-x$
    \text{=2}$x^{3}+2x$
