10 divided by the difference of a number and 2 minus 9 divided by a number plus 2, equals 3 times the recipricol of the difference of the number squared and 4. what is the number?
+%2810%2F%28x-2%29%29-%289%2F%28x%2B2%29%29+=+3%2A%281%2F%28x%5E2-4%29%29


Multiply by the LCM x%5E2-4%29
10(x+2)-9(x-2)=3*1
10x+20-9x+18=3
x+38=3
x=-35
