If _ x 0 (2+x)- (2-x) x =A B , then the values of A and B respectively are

Options

  1. A1,2
  2. B2,1
  3. C1,1
  4. D2,2

Correct answer

D. 2,2

Step-by-step solution

We have, _ x 0 (2+x)- (2-x) x =A B _ x 0 2 ( 2+x+2-x 2 ) ( 2+x-2+x 2 ) x aligned & = _ x 0 2 2 x x & =2 2 _ x 0 x x =2 2 aligned Thus, A=2 and B=2
