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

expand

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

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

Solution steps

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

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

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

Expand

2 (- x + 2) : - 2 x + 4

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

\frac{1}{2} (e^{t} + e^{- t})

(A e^{- k x} + B e^{k x})^{2}

im x \Rightarrow - 2 (x^{3} + 8 x + 2)

\frac{( x + y ) ^{2}}{x y}

\frac{1}{( y + 2 ) ( y - 5 ) ( y + 7 )}
