expand (xsqrt(1+x^2))/(2(sqrt(1+x^2)+1+x^2))

expand

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

\frac{x 1 + x ^{2}}{2 1 + x ^{2} + 2 + 2 x ^{2}}

Solution steps

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

Expand

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

= \frac{x x ^{2} + 1}{2 x ^{2} + 1 + 2 + 2 x ^{2}}

(210) \cdot (1 - e^{- \frac{t}{1.8}})

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

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

\frac{( 0.11423 ( s + 7.646 ) ( s + 1.167 ) )}{s}

\frac{1}{( 3 x + 1 ) ^{3}}
