Complex Fractions.
LCM: (b+3)(b-3)

  1. Steve

    Try typing in your expression at

    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.

    I am stumped by these two LCM questions for some reason. Find The LCM for #1 2(R-7) and 14(R-7) #2 (1+4r), (1-16r^2), and (1-4r) It seems like #1 is already at the LCM and #2 would be (1+4r)(1-4r) Am I even vaguely correct?
