The board won't space as you want it to space. You will need to retype your question using parentheses and / for divide. For example, if you meant,\
[1/(x+2)] + [.... etc)].
Please Simplify:

Sorry about that! here it is again!
1/x+2 + 4/x^2-4
1/x+2 + 4/x^2-4
1 / (x+2) + 4 / [(x+2)(x-2)]
= (x-2) / [(x+2)(x-2) ] + 4 / [(x+2)(x-2)]
= (x+2) / [(x+2)(x-2)]
= 1/(x-2)
= (x-2) / [(x+2)(x-2) ] + 4 / [(x+2)(x-2)]
= (x+2) / [(x+2)(x-2)]
= 1/(x-2)
