    To simplify the expression, we can check if there are terms that are needed to be added or subtracted. In this case, there are none. We get the factors of 4 equations present in the expression.

    x^2+x-12 = {3,-4}

    x^2-x-20 = {5,-4}

    3x^2-24+45 = {5,3}

    12x^2-48x-60 = {5,-1}

    hence we cancel 5 and from numerator and denominator.

    the answer is (x+4) ^2 / (x-5) * (x+1)
