Answer 2

To simplify the given expression, let's break it down step by step:

(4 - 2a)² - (3a - 2)(6 - a) + a²

Step 1: Expand the square term (4 - 2a)² (4 - 2a)² = (4 - 2a)(4 - 2a) Expanding using the FOIL method: = 16 - 8a - 8a + 4a² = 16 - 16a + 4a²

Step 2: Expand the product (3a - 2)(6 - a) (3a - 2)(6 - a) Expanding using the FOIL method: = 18a - 3a² - 12 + 2a = -3a² + 20a - 12

Step 3: Combine like terms Now let's combine all the terms we have obtained so far: (16 - 16a + 4a²) - (-3a² + 20a - 12) + a²

Step 4: Distribute the negative sign across the parentheses = 16 - 16a + 4a² + 3a² - 20a + 12 + a²

Step 5: Combine like terms = 4a² + 3a² + a² - 16a - 20a + 12 + 16

Step 6: Simplify the expression = 8a² - 36a + 28

Therefore, the simplified form of the expression (4 - 2a)² - (3a - 2)(6 - a) + a² is 8a² - 36a + 28.
