Options

  1. A0
  2. B1
  3. C^2 2
  4. D^2

Correct answer

D. ^2

Step-by-step solution

Given expression, aligned & 1+ 2 (2 -2 ) ( - 3 4 ) & - 1 4 2 [ 2 + ( 3 2 + 2 ) ] & ( + )^2 2 ( - 3 4 1+ 3 4 ) & - 1 4 2 ( 2 - 2 ) & = ( + )^2 ^2 - ^2 ( +1 1- ) & - 1 4 2 ( 2 2 - 2 2 ) & = ( + ) ( - ) ( - ) ( + ) & - 1 2 ( ^2 2 - ^2 2 2 2 ) & =1- ^2 2 2 2 =1- ^2 & =1- ^2 = ^2 & aligned
