please guys help

express as a single fraction (1/x)-(2/x-2)+(x-1/x^2+1)

and (x+1/x^2+1)+(1/x+1)-(1/(x-1)^2)+(2/x-2)

just put everything to the same denominator then simplify, factorise and cut out the redundant values.

As furor celtica said you need to make everything have the same denominator, which for your question would be:

$\displaystyle \frac{A}{x(x-2)(x^2+1)}$

For the numerator you need to multiply each term by the other 2 denominator, for example:

$\displaystyle \frac{1(x-2)(x^2+1)...}{x(x-2)(x^2+1)}$.

Repeat this method for your other question.

okay guys plese could you confirm my answers

1.x-5x^2-2/x(x-2)(x^2+1)

2.x^3-x^2+2x/x^2-1
