    hmm, your formula is not very clear:

    if you mean:

    (3x^2 - 4x) / (18x^2 - 5x^2) = (3x^2 - 4x) / 13x^2 = 3x^2 / 13x^2 - 4x/13x^2 = 3/13 - 4/13x = 3/13 (4/13x limits to 0)

    if you mean:

    (3x^2 - 4x) / 18x^2 - 5x^2 = 3x^2/18x^2 - 4x/18x^2 - 5x^2 = 3/18 - 4/18x - 5x^2 = -infinity

    The value of this limit is not infinity but is 3/13 apply L'Hospital's Rule

    since it is of infinity by infinity form
