(dy)/(dx)=x*e^{-2x},y(0)=3

\frac{d y}{d x} = x \cdot e^{- 2 x}, y (0) = 3

y = \frac{1}{4} (- 2 e^{- 2 x} x - e^{- 2 x}) + \frac{13}{4}

Solution steps

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

Substitute

\frac{d y}{d x}

with

y^{'} (x)

y^{^{'}} (x) = x e^{- 2 x}

f^{^{'}} (x) = g (x)

then

f (x) = \int g (x) d x

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

\int x e^{- 2 x} d x = \frac{1}{4} (- 2 e^{- 2 x} x - e^{- 2 x}) + c_{1}

y = \frac{1}{4} (- 2 e^{- 2 x} x - e^{- 2 x}) + c_{1}

Apply initial conditions:

y = \frac{1}{4} (- 2 e^{- 2 x} x - e^{- 2 x}) + \frac{13}{4}

y = \frac{1}{4} (- 2 e^{- 2 x} x - e^{- 2 x}) + \frac{13}{4}
