((25/a)- a)/ (5 + a)

I know the answer comes to (5-a)/a but I can't figure out how to simplify it to this. I've gotten close but I'm not sure. Its probably easier than I'm making it out to be.

  • Math -

    Try multiplying by a/a.

  • Math -

    easiest way.....
    multiply top and bottom of the main fraction by a to get
    (25-a^2) / (a(5+a) )
    = (5+a)(5-a)/(a(5+a) )
    = (5-a)/a
