%28a+-+1%29%2F%281%5E2+-+4%29+%2B+1%2F%28+1+-+2%29+=+%28a+%2B+4%29%2F%28+a+%2B+2%29
%28a+-+1%29%2F%28+-+3%29+%2B+1%2F%28-1%29+=+%28a+%2B+4%29%2F%28+a+%2B+2%29
-%28a+-+1%29%2F3+-+1+=+%28a+%2B+4%29%2F%28+a+%2B+2%29.....both sides multiply by 3%28a%2B2%29+

-%28a+-+1%29%28a%2B2%29+-3%28a%2B2%29+=+3%28a+%2B+4%29
%28-a+%2B+1%29%28a%2B2%29+-3a%2B6+=+3a+%2B+12
-a%5E2-2a%2Ba%2B2+-3a%2B6+=+3a+%2B+12
-a%5E2-4a%2B8+=+3a+%2B+12
-a%5E2-4a%2B8-3a-+12=0
-a%5E2-7a-4=0
