DO you know how to simplify it now?

x^2 3x ------- - --------- = x/(x+2) - 3x/(x^2 -1) x(x+2) x^2 -1 - so now you need getting the denominator common can you calcule it ?

Christian -- this is understandably for you ?

Is that not a divide sign in between the two of them?
anonymous
  • anonymous
Yeah it is a divide sign
jhonyy9
  • jhonyy9
so than you need multiply first fraction by second inversed
jhonyy9
  • jhonyy9
ok ?
jhonyy9
  • jhonyy9
so than x/(x+2) * (x^2 -1)/3x = (x^2 -1)/(x+2) = (x-1)(x+1)/(x+2)

ok ?
