expand-(49x)/((1+7x)^2)

expand

- \frac{49 x}{( 1 + 7 x ) ^{2}}

- \frac{49 x}{1 + 14 x + 49 x ^{2}}

Solution steps

- \frac{49 x}{( 1 + 7 x ) ^{2}}

(1 + 7 x)^{2} = 1 + 14 x + 49 x^{2}

= - \frac{49 x}{49 x ^{2} + 14 x + 1}

x (2 x - 2 x - 4)

\frac{( ( x + 1 ) ^{2} )}{x ^{2} - s - 6}

\frac{( x - 1 ) ^{2} + 2 ( x - 1 ) x ^{\frac{1}{13}}}{13 x ^{\frac{12}{13}}}

4 (4 x ln (x) + 2 x)

\frac{1486}{6}
