( x ( ^2 x ) d x= )
Options
- A(x (x)- _e( x)- x^2 2 +c )
- B(x (x)+ _e( x)- x^2 2 +c )
- C(x (x)- _e( x)+ x^2 2 +c )
- D(x (x)+ _e( x)+ x^2 2 +c )
Correct answer
A. (x (x)- _e( x)- x^2 2 +c )
Step-by-step solution
( aligned I & = x ( ^2 x ) d x=x ( ^2 x-1 ) d x - (1 ( ^2 x-1 ) d x ) d x & =x( x-x)- ( x-x) d x & =x x-x^2- _e( x)+ x^2 2 +C & =x x- _e( x)- x^2 2 +C aligned ) Hence, option (a) is correct.
