expand ((e+1)(e-1))/(e^2+1)

expand

\frac{( e + 1 ) ( e - 1 )}{e ^{2} + 1}

\frac{e ^{2} - 1}{e ^{2} + 1}

Decimal Notation

0.76159 \dots

Solution steps

\frac{( e + 1 ) ( e - 1 )}{e ^{2} + 1}

Expand

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

= \frac{e ^{2} - 1}{e ^{2} + 1}

\frac{b ^{2} ( 4 a ^{3} b ^{2} - 3 )}{a}

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

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

\frac{( x + 3 )}{( x + 2 ) ^{2}}

(x + 5) e^{0.02 x + 1}
