Khalil was asked to determine whether (+2)(x2 – 2x +4) = x* + 8z represents a polynomial identity. He states that this relationship is not true and the justification he used is below. Step 1: (x + 2)(2² - 2x + 4) Step 2: (- 2z? + 4x)(x + 2) Step 3: -2a + 8x2 - 2x3+822 +8x Step 4: 4x3 +16x2 + 8x Which statement correctly describes Khalil's justification Statement A Khalil is correct. There are no mistakes in his justification. Khalil made a mistake in step 2. The justification should be Statement B (22 +2z)(2- 2x +4). Statement C Khalil made a mistake in step 3. The justification should be z + 8x. Statement D Khalil made a mistake in step 4. The justification should be +4x +16x2 + 8x O Statement B O Statement D O Statement C O Statement A
