( \frac{x^2 - x -12}{2x} ) ÷ ( \frac{x^2 - 2x - 8}{4x^2} )

= ( \frac{x^2 - x -12}{2x} ) × ( \frac{4x^2}{x^2 - 2x - 8} )

= \frac{x(x^2 - x -12)}{x^2 - 2x - 8}

= \frac{x(x^2 -4x +3x -12)}{x^2 -4x +2x -8}

= \frac{x[x(x - 4) +3(x - 4)]}{x(x - 4) +2(x - 4)}

= \frac{x(x-4)(x+3)}{(x-4)(x+2)}

= \frac{x(x+3)}{(x+2)}
