The simplified form of the given expression is; (a+1) (1/(a-6) - (a-6)/(a+6)(a+3).
Simplification of polynomial expressions
The polynomial expression given is;
- a²-2a-3/a²-9a+18 - a²-5a-6/a²+9a+8.
Hence, it follows from factorisation that;
- (a-3)(a+1)/(a-6)(a-3) - (a-6)(a+1)/(a+6)(a+3)
Hence, it follows from simplification that;
- (a+1)/(a-6) - (a-6)(a+1)/(a+6)(a+3)
- (a+1) (1/(a-6) - (a-6)/(a+6)(a+3).
