( 4 (x+ 6 ) 2 x ( 5 6 +x ) d x )
Options
- A(- (x+ 4 x 4 + 2 x 2 )+c )
- B(- (x+ 4 x 4 - 2 x 2 )+c )
- C(- (x- 4 x 4 + 2 x 2 )+c )
- D(- (x- 4 x 4 + 2 x 2 )+c )
Correct answer
A. (- (x+ 4 x 4 + 2 x 2 )+c )
Step-by-step solution
( aligned & 4 (x+ 6 ) 2 x ( 5 6 +x ) d x & =2 ( (2 x+ ) 2 3 ) 2 x d x & =2 (- 2 x- 1 2 ) 2 x d x & = (-2 ^2 2 x- 2 x ) d x & =- (1+ 4 x+ 2 x) d x & =-x- 4 x x - 2 x 2 +c aligned )
