5x/x+3+28/x-3-90/x^2-9

**Reiny**, Sunday, April 1, 2012 at 9:03pmI think you mean

5x/(x+3) + 28/(x-3) - 90/(x^2 - 9)

the LCD is (x+3)(x-3) or (x^2-9)

= ( 5x(x-3) + 28(x+3) - 90)/(x^2-9)

= (5x^2 - 15x + 28x + 84 -90)/(x^2 - 9)

= (5x^2 + 13x - 6)/(x^2 - 9)

= (x+3)(5x-2) /( (x+3)(x-3) )

= (5x-2)/(x-3)
