    I got ( X-8 ) / ( X+2 )

    they are both quadratic equations:

    the numerator simplifies to (X-2)(X-8)

    the denominator simplifies to (X-2)(X+2)

    the common multiplier is (X-2) and so it cancels out, leaving us with the above answer.

    I can't say for sure but often with problems like that, they mean factor and simplify:

    (x - 8)(x - 2)

    ------------------

    (x + 2)(x - 2); the (x - 2)'s cancel so

    (x - 8)

    --------

    (x + 2)
