expand-9/(x(2+ln(7x))^2)

expand

- \frac{9}{x ( 2 + ln ( 7 x ) ) ^{2}}

- \frac{9}{4 x + 4 x ln ( 7 x ) + x ln ^{2} ( 7 x )}

Solution steps

- \frac{9}{x ( 2 + ln ( 7 x ) ) ^{2}}

(2 + ln (7 x))^{2} = 4 + 4 ln (7 x) + ln^{2} (7 x)

= - \frac{9}{x ( ln ^{2} ( 7 x ) + 4 ln ( 7 x ) + 4 )}

Expand

x (4 + 4 ln (7 x) + ln^{2} (7 x)) : 4 x + 4 x ln (7 x) + x ln^{2} (7 x)

= - \frac{9}{4 x + 4 x ln ( 7 x ) + x ln ^{2} ( 7 x )}

\frac{g ( x - a ) ( x - c )}{( f - a ) ( f - c )}

(u y + y) (u d y + y d u)
