expand (0.3e^{-x}+0.4+0.3e^x)^2

expand

(0.3 e^{- x} + 0.4 + 0.3 e^{x})^{2}

0.24 e^{x} + 0.09 e^{- 2 x} + 0.09 e^{2 x} + 0.24 e^{- x} + 0.34

Solution steps

(0.3 e^{- x} + 0.4 + 0.3 e^{x})^{2}

(0.3 e^{- x} + 0.4 + 0.3 e^{x})^{2} = (0.3 e^{- x} + 0.4 + 0.3 e^{x}) (0.3 e^{- x} + 0.4 + 0.3 e^{x})

= (0.3 e^{x} + 0.3 e^{- x} + 0.4) (0.3 e^{x} + 0.3 e^{- x} + 0.4)

Expand

(0.3 e^{- x} + 0.4 + 0.3 e^{x}) (0.3 e^{- x} + 0.4 + 0.3 e^{x}) : 0.24 e^{x} + 0.09 e^{- 2 x} + 0.09 e^{2 x} + 0.24 e^{- x} + 0.34

= 0.24 e^{x} + 0.09 e^{- 2 x} + 0.09 e^{2 x} + 0.24 e^{- x} + 0.34

\frac{( 6 + x ) ^{2}}{36}

\frac{a \cdot b}{( s ^{2} \cdot ( b \cdot c + a \cdot c ) + s \cdot a \cdot b )}

- (\frac{( x - 2 ) ^{2}}{8}) + 8

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