  1. (x^2+x-6)/(x^2-4) = (x-2)(x+3) / (x-2)(x+2)

    Now divide that by (x+3) / 2(x+2)
    or, equivalently, multiply by 2(x+2)/(x+3)

    Lots of factors cancel.

    Not sure how far to take this problem down. The directions say to simplify using the distributive property. 4(x + 1) -2 divided by 2. Would it be 4x +4 -2 divided by 2 or 4x + 2 divided by 2 or 2x +1? Thanks..
