expand-(10(-x+2))/((x+1)^4)

expand

- \frac{10 ( - x + 2 )}{( x + 1 ) ^{4}}

- \frac{- 10 x + 20}{x ^{4} + 4 x ^{3} + 6 x ^{2} + 4 x + 1}

Solution steps

- \frac{10 ( - x + 2 )}{( x + 1 ) ^{4}}

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

= - \frac{10 ( - x + 2 )}{x ^{4} + 4 x ^{3} + 6 x ^{2} + 4 x + 1}

Expand

10 (- x + 2) : - 10 x + 20

= - \frac{- 10 x + 20}{x ^{4} + 4 x ^{3} + 6 x ^{2} + 4 x + 1}

(4 x^{2} - \frac{3}{2 x})^{12}

- \frac{sec ^{2} ( \frac{x}{2} )}{( tan ( \frac{x}{2} ) - 1 ) ^{2}}

- \frac{1}{8} (36 x - 16 y)

x \cdot (1 - x - y) \cdot e^{y}

\frac{x ^{2} - 9}{x ( x ^{2} + 1 )}
