  2. 1.) y' + 4y = 2x*e^(-4x) Integrating factor = e^(∫4 dx) = e^(4x) Multiply both sides of the D.E by the integrating factor: y'*e^(4x) + 4*e^(4x)y = 2x d/dx[y*e^(4x)] = 2x y*e^(4x) = x² + C y = x²*e^(-4x) + C*e^(-4x) 2.) xy...

  3. xy y' = x² + y² y' = (x/y) + (y/x) let y = xv ; y' = xv' + v xv' = 1/v ∫ v dv = ∫ 1/x dx v² = 2 ln|x| + C₁ (y/x)² = 2 ln|x| + C₁ y = ± x √(2 ln|x| + C₁) Answer: y = ± x √(2 ln|x| + C₁)
