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

expand

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

2 e^{2 x} - 2 e^{- 2 x}

Solution steps

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

Expand

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

= 2 (e^{2 x} - e^{- 2 x})

Expand

2 (e^{2 x} - e^{- 2 x}) : 2 e^{2 x} - 2 e^{- 2 x}

= 2 e^{2 x} - 2 e^{- 2 x}

\frac{3 ( 5 x - 6 )}{2}

\frac{10}{( s + 1 ) ( s + 2 )}

(2 x - ux) u d x + x d u

(a + b + c) \cdot (d + e + f)

\frac{( 4 h + 3 k - 4 ) ^{2}}{25}
