    .........2x^2 - x - 1

    lim ------------------

    x->1..(x - 1)^2

    .......(2x + 1)(x - 1)

    lim --------------------- cancel out x - 1

    x->1..(x - 1)(x - 1)

    ........2x + 1

    lim -------------

    x->1.x - 1

    ....2(1) + 1

    =---------------

    ......1 - 1

    (2x^2-x-1)/(x-1)^2

    (x-1)(2x+1)/(x-1)^2

    (2x+1)/(x-1)

    Take limit

    (2(1)+1)/((1)-1)

    3/0

     = infinity
