    find a common denominator for the tops, and subtract ditto for the bottom fractions then change the division by a fraction by inverting the bottom fraction and then multiplying

    multiply top and bottom by \((x+2)(x-2)\) cancelling merrily as you go clears the compound fraction in one step

    is the problem \[ \frac{ \frac{3}{2+x}-\frac{4}{2-x}}{\frac{1}{x+2}-\frac{3}{x-2}}\]
