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

expand

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

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

Solution steps

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

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

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

(e^{x} + ln (y) + \frac{y}{x}) d x + (\frac{x}{y} + ln (x) + sin (x)) d y

\frac{e ^{s}}{s ( 1 - e ^{- s} )}

\frac{( - x + 2 y ) ^{2}}{x + 2 y}

\frac{( 2 s ^{2} + s + 2 )}{( s ^{2} + 3 s + 7 ) ( s ^{2} + 1 )}

\frac{x ^{3} - m x ^{2} + ( 10 m - 15 ) x - 15 m - 30}{x - 5}
