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

expand

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

- \frac{2 x + 1}{x ^{4} + 2 x ^{3} + 3 x ^{2} + 2 x + 1}

Solution steps

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

(1 + x + x^{2})^{2} = x^{4} + 2 x^{3} + 3 x^{2} + 2 x + 1

= - \frac{2 x + 1}{x ^{4} + 2 x ^{3} + 3 x ^{2} + 2 x + 1}

5 (3 + 2)

(x - 1) (x + 2 i) (x - 2 i)

(\frac{1}{12}) (t) (L + \frac{t}{2} + \frac{R}{2})^{3}

\frac{110 ( ln ( x ) - 2 )}{x}

2 (x^{3} sin (x^{3}) + cos (x^{3}) - 1)
