expand (4(-x^6+81x^2))/((x^4+27)^2)

expand

\frac{4 ( - x ^{6} + 81 x ^{2} )}{( x ^{4} + 27 ) ^{2}}

\frac{- 4 x ^{6} + 324 x ^{2}}{x ^{8} + 54 x ^{4} + 729}

Solution steps

\frac{4 ( - x ^{6} + 81 x ^{2} )}{( x ^{4} + 27 ) ^{2}}

(x^{4} + 27)^{2} = x^{8} + 54 x^{4} + 729

= \frac{4 ( - x ^{6} + 81 x ^{2} )}{x ^{8} + 54 x ^{4} + 729}

Expand

4 (- x^{6} + 81 x^{2}) : - 4 x^{6} + 324 x^{2}

= \frac{- 4 x ^{6} + 324 x ^{2}}{x ^{8} + 54 x ^{4} + 729}

(x + 2)^{'} \cdot (x) - (x + 2) \cdot (x)^{'}

\frac{( k ^{2} + 3 k + 2 ) ^{2}}{4}

(x^{2} - 4 \circ x - 2) (x)

(- 5, - 5) y (- 10, 20)

2 x y (3 y - x - 1)^{2}
