    \frac{3x-6}{x^2-4x+4}

    =\frac{3(x-2)}{(x-2)^2}<br />

    =\frac{3}{x-2}

    3/y-3 - 4/y+3
    \frac{3}{y-3}-\frac{4}{y+3}

    =\frac{3(y+3)}{(y-3)(y+3)}-\frac{4(y-3)}{(y+3)(y-3)}

    =\frac{3(y+3)-4(y-3)}{(y-3)(y+3)}

    =\frac{3y+9-4y+12}{(y-3)(y+3)}

    =\frac{3-y}{(y-3)(y+3)}

    =\frac{-(y-3)}{(y-3)(y+3)}

    =\frac{-1}{y+3}

    Did you get it now ???
