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

expand

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

e^{- 4 t} + 4 e^{- 2 t} + e^{4 t} + 4 e^{2 t} + 6

Solution steps

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

(e^{2 t} + e^{- 2 t} + 2)^{2} = (e^{2 t} + e^{- 2 t} + 2) (e^{2 t} + e^{- 2 t} + 2)

= (e^{2 t} + e^{- 2 t} + 2) (e^{2 t} + e^{- 2 t} + 2)

Expand

(e^{2 t} + e^{- 2 t} + 2) (e^{2 t} + e^{- 2 t} + 2) : e^{- 4 t} + 4 e^{- 2 t} + e^{4 t} + 4 e^{2 t} + 6

= e^{- 4 t} + 4 e^{- 2 t} + e^{4 t} + 4 e^{2 t} + 6

(- 5 x - 3) (2 x + 1)^{''}

7 + \frac{1}{5}

5 a^{6 - 1}

t^{(x^{2} - x + 2) d x}

π (x + 1 + 6)^{2}
