expand ln(x^2+1)+x^2(2xarctan(x)-1)6

expand

ln (x^{2} + 1) + x^{2} (2 x arctan (x) - 1) 6

ln (x^{2} + 1) + 12 x^{3} arctan (x) - 6 x^{2}

Solution steps

ln (x^{2} + 1) + x^{2} (2 x arctan (x) - 1) \cdot 6

= ln (x^{2} + 1) + 6 x^{2} (2 x arctan (x) - 1)

Expand

x^{2} \cdot 6 (2 x arctan (x) - 1) : 12 x^{3} arctan (x) - 6 x^{2}

= ln (x^{2} + 1) + 12 x^{3} arctan (x) - 6 x^{2}

\frac{( x ^{4} + x )}{x}

\frac{( s + 3 ) ( s + 2 )}{( s + 1 ) ( s ^{2} + 2 s + 3 )}

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

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