expand x^2+(x+4)e^{-x}

expand

x^{2} + (x + 4) e^{- x}

x^{2} + e^{- x} x + 4 e^{- x}

Solution steps

x^{2} + (x + 4) e^{- x}

= x^{2} + e^{- x} (x + 4)

Expand

e^{- x} (x + 4) : e^{- x} x + 4 e^{- x}

= x^{2} + e^{- x} x + 4 e^{- x}

\frac{sin ( 2 x )}{2 cos ^{2} ( x ) \cdot ( 1 + cos ( x ) )}

\frac{\partial}{\partial x} ((f (x, y)) (x^{2} - 2 x y))

\frac{e ^{- x} \cdot ( x ^{2} + 2 )}{x ^{2} + 3 \cdot x + 2}

(3 y^{\frac{1}{3}} = \frac{1}{2} x^{2} + C) \frac{1}{3}

\frac{4 ( r + 1 ) ^{3}}{3}
