expand ((e^{1.1x}-e^{-1.1x}))^2

expand

((e^{1.1 x} - e^{- 1.1 x}))^{2}

e^{2.2 x} - 2 + e^{- 2.2 x}

Solution steps

(e^{1.1 x} - e^{- 1.1 x})^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

a = e^{1.1 x}, b = e^{- 1.1 x}

= (e^{1.1 x})^{2} - 2 e^{1.1 x} e^{- 1.1 x} + (e^{- 1.1 x})^{2}

Simplify

(e^{1.1 x})^{2} - 2 e^{1.1 x} e^{- 1.1 x} + (e^{- 1.1 x})^{2} : e^{2.2 x} - 2 + e^{- 2.2 x}

= e^{2.2 x} - 2 + e^{- 2.2 x}

e^{(4 x)} (4 x - 16)

\frac{( 3 ^{(n + 1) (n + 2)} + 65 )}{72}

e^{x} (x^{2} - 2 x - 7)

\frac{x + 2}{( x + 3 ) ^{\frac{5}{4}}}

e^{a (s - 1)} + e^{b (s - 1)}
