1+ A =- ( A 2 + A 2 ) is true if

Options

  1. A3 2 A 5 2 only
  2. B2 A 3 2 only
  3. C3 2 A 7 2
  4. D0 A 3 2

Correct answer

C. 3 2 A 7 2

Step-by-step solution

1+ A =- ( A 2 + A 2 ) We know, 1+ A = ( A 2 + A 2 )^2 1+ A = | A 2 + A 2 | We know, |x|= array c x if x 0 -x if x 0 array . | A 2 + A 2 |= cases A 2 + A 2 , & if 2 n - 4 A 2 2 n + 3 4 - ( A 2 + A 2 ), & if otherwise cases 1+ A =- ( A 2 + A 2 ) when, 3 4 A 2 7 4 3 2 A 7 2 .
