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

\frac{4 ( x - 1 ) ^{3} ( - x ^{2} + 2 x + 2 )}{( x ^{2} + x + 1 ) ^{5}}

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

4 (\frac{x - 1}{x ^{2} + x + 1})^{3} \frac{- x ^{2} + 2 x + 2}{( x ^{2} + x + 1 ) ^{2}} : \frac{4 ( x - 1 ) ^{3} ( - x ^{2} + 2 x + 2 )}{( x ^{2} + x + 1 ) ^{5}}

= \frac{4 ( x - 1 ) ^{3} ( - x ^{2} + 2 x + 2 )}{( x ^{2} + x + 1 ) ^{5}}
