यदि $A = \begin{bmatrix} a & b \\ b & a \end{bmatrix}$ और $A^2 = \begin{bmatrix} \alpha & \beta \\ \beta & \alpha \end{bmatrix}$ है,तो:

• A
  $\alpha = a^2 + b^2, \beta = ab$
• B
  $\alpha = a^2 + b^2, \beta = 2ab$
• C
  $\alpha = a^2 + b^2, \beta = a^2 - b^2$
• D
  $\alpha = 2ab, \beta = a^2 + b^2$
