b-2b/b+3/1/b+3+1/b-3=
LCM: (b+3)(b-3)

  • Algebra -

    Try typing in your expression at wolframalpha.com

    and keep adding parentheses until it interprets your text correctly!

    I suspect you mean

    b - 2b/(b+3)
    -----------------
    1/(b+3) + 1/(b-3)

    If not, maybe you can clear things up a bit. Online text formatting requires a bit more effort.
