( e^ x ( x+1 x ) d x ) is equal to
Options
- A( x e^ x +C )
- B( x e^ x +C )
- C( e^ x +C )
- D( e^ x ( x+1)+C )
Correct answer
A. ( x e^ x +C )
Step-by-step solution
Given that, ( e^ x ( x+1 x ) d x ) [ = e^ x ( x x+ x) d x ] We know that, [ array l e^ g(x) (g^ (x) f(x)+f^ (x) ) d x=e^ g(x) f(x)+c So, e^ x ( x+1 x ) d x=e^ x x+c array ]
