(e^ ( x) + x ) x , dx =
Options
- Ax( x + x) + ( x - x) + c
- Bx( x - x) + ( x - x) + c
- Cx( x + x) + ( x + x) + c
- Dx( x - x) + ( x + x) + c
Correct answer
D. x( x - x) + ( x + x) + c
Step-by-step solution
Using the property e^ f(x) = f(x) , the given integral simplifies to: x( x + x) dx Applying integration by parts, taking x as the first function and ( x + x) as the second function: x( x + x) dx = x ( x + x) dx - ( d dx (x) ( x + x) dx ) dx = x( x - x) - 1 ( x - x) dx = x( x - x) - (- x - x) + c = x( x - x) + ( x + x) + c Answer: x( x - x) + ( x + x) + c
