    Simplify the expression first by the "flip and multiply" method. We end up first with:

    [x (x-3) ]/[x⁻¹ (x+4) ]

    Simplifying further we have:

    [x² (x-3) ] / (x+4)

    Solving for restriction we equate the denominator to 0:

    x + 4 = 0

    x = - 4

    x≠4 (-4 is a restriction of the expression)
