integral of 2xe^{-y}

Solution

\int 2 x e^{- y} d x

Solution

e^{- y} x^{2} + C

Solution steps

\int 2 x e^{- y} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 e^{- y} \cdot \int x d x

Apply the Power Rule

: \frac{x ^{2}}{2}

= 2 e^{- y} \frac{x ^{2}}{2}

Simplify

2 e^{- y} \frac{x ^{2}}{2} : e^{- y} x^{2}

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

Add a constant to the solution

= e^{- y} x^{2} + C
