2 x- 2 x- d x is equal to

Options

  1. A2( x-x )+c
  2. B2( x+x )+c
  3. C2( x-2 x )+c
  4. D2( x+2 x )+c

Correct answer

B. 2( x+x )+c

Step-by-step solution

aligned & L=1= 2 x- 2 x- d x & I= (2 ^2 x-1 )- (2 ^2 -1 ) x- d x & I=2 ^2 x- ^2 x- d x aligned aligned & =2 ( x- (x)( x+ ) ( x- ) d x & =2 ( x+ ) d x=2( x+x )+c aligned
