ok ! but anyway , thanks for your solution .

sorry ! because i type the wrong ques ! could you show me again ! thanks ...

er ... sorry ! i posted the wrong ques ... actually is ... hence ,find the constant term in the expansion if (1+x^2)/(-3x(1+x)(1+2x)) in ascending power of x .

can anyone show me how to do this question ? thanks ... express (1+x^2)/((1+x)(1+2x)) in partial fraction. (this step i know the solution ) hence,find the constant term in the expansion if (1+x^2)/(-3x(1+x)(1+2x)) in ascending power of x .( then this one don't know ,please help me ) thanks ...
