    one way it so multiply top and bottom by \(81x^2\) to clear the complex faction after that you will factor and cancel

    stake out common factors. 9x^2 - 81x is the same as 9x(x-9) and x^2-81 is the same as (x+9)(x-9). Cancel the common factors and there's your answer :)

    your answers should be 9x/(x+9)
