Simplify Radicals?

I have (x+3)/sqrt(9x^2+5x)

I thought you would just multiply top and bottom by sort(9x^2-5x) to clear the radical. However, the answer shows sort((x^2+6x+9)/(9x^2-5x)

What have they done here?

    What you wrote as sort((x^2+6x+9)/(9x^2-5x) makes no sense, starting from "sort" (sqrt?) and the fact that the parenthesis do not match. Sqrt of what?

    Repost and clean up and CHECK what you post.
