    Constant term in expansion of (1+x²)/(-3x(1+x)(1+2x))

    because i want the step solution ! because i had do the one solution ,but teacher say the working are wrong !

    ok ! but anyway , thanks for your solution .

    Constant term in expansion of (1+x²)/(-3x(1+x)(1+2x))

    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 .

    Constant term in expansion of (1+x²)/(-3x(1+x)(1+2x))

    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 ...
