expand 2/((x^6+x^2+1)^2)

expand

\frac{2}{( x ^{6} + x ^{2} + 1 ) ^{2}}

\frac{2}{x ^{12} + 2 x ^{8} + 2 x ^{6} + x ^{4} + 2 x ^{2} + 1}

Solution steps

\frac{2}{( x ^{6} + x ^{2} + 1 ) ^{2}}

(x^{6} + x^{2} + 1)^{2} = x^{12} + 2 x^{8} + 2 x^{6} + x^{4} + 2 x^{2} + 1

= \frac{2}{x ^{12} + 2 x ^{8} + 2 x ^{6} + x ^{4} + 2 x ^{2} + 1}

(1 + x^{4} + x^{6})^{7}
