expand 1/((x^2+x+1)^3)

expand

\frac{1}{( x ^{2} + x + 1 ) ^{3}}

\frac{1}{x ^{6} + 3 x ^{5} + 6 x ^{4} + 7 x ^{3} + 6 x ^{2} + 3 x + 1}

Solution steps

\frac{1}{( x ^{2} + x + 1 ) ^{3}}

(x^{2} + x + 1)^{3} = x^{6} + 3 x^{5} + 6 x^{4} + 7 x^{3} + 6 x^{2} + 3 x + 1

= \frac{1}{x ^{6} + 3 x ^{5} + 6 x ^{4} + 7 x ^{3} + 6 x ^{2} + 3 x + 1}
