  1. Let ( u = x^2 ), ( dv = e^x dx ).
  2. Then ( du = 2x dx ), ( v = e^x ).
  3. Apply formula: ( \int u , dv = uv - \int v , du ).
  4. = ( x^2 e^x - \int e^x \cdot 2x , dx ).
  5. For ( \int 2x e^x dx ), use parts again: Let ( u = 2x, dv = e^x dx ) → ( du = 2dx, v = e^x ).
  6. = ( 2x e^x - \int 2 e^x dx = 2x e^x - 2e^x + C' ).
  7. Combine: ( x^2 e^x - (2x e^x - 2e^x) + C = e^x (x^2 - 2x + 2) + C ).
