Given, 4 x 4 + 1 To make it a perfect square we need to add and subtract 4 x 2 Thus, 4 x 4 + 1 = 4 x 4 + 1 + 4 x 2 - 4 x 2 ⇒ 4 x 4 + 1 + 4 x 2 - 4 x 2 ⇒ 2 x 2 2 + 2 × 2 x 2 × 1 + 1 2 - 2 x 2 ⇒ 2 x 2 + 1 2 - 2 x 2 ⇒ 2 x 2 + 1 + 2 x 2 x 2 + 1 - 2 x Hence, the required answer is 2 x 2 + 1 + 2 x 2 x 2 + 1 - 2 x .
