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

expand

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

\frac{3 x ^{2}}{x ^{6} + 2 x ^{3} + 1}

Solution steps

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

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

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

(1 - i 3)^{4}

(1 + x^{2}) arctan (x) - x

(1 - 2 i)^{10}

a (- 1 - 3) b (5, 5) c (6, - 2)
