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

expand

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

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

Solution steps

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

(1 + x)^{2} = 1 + 2 x + x^{2}

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

- 2 e^{2 x} (e^{- 2 x} + 1)^{2}

(x^{3} - 2 x^{2} - 5 x) (x - 1)^{'}

(1, - 2, 0) X (2, 1, 0)

[- (x - 6)]^{2}

\frac{k}{s ( s ^{2} + 9 s + 9 )}
