1.) 2x/2x^2+5x-3 + 5/x^2-9 =

2.) x-3/12x^3-18x^2 - x+1/16x^2-24x =

3.) 2x/x^2-2x-15 - x-2/3x^2+9x =

**drwls**, Monday, August 27, 2012 at 9:51amUse parentheses to isolate numerators and denominators. For example,

3.) 2x/(x^2-2x-15) - (x-2)/(3x^2+9x)

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

= [1/(x+3)][2x/(x-5) + (x-2)/(3x)]
