Question

Aa6)a2 + 16a + 4 16 – a?4a + a2(4 – a)²​

Answer 1

Ответ:

а2+16=(а+4)(а+4)

4а+а2=а(4+а)

(4-а)(во второй) =(4-а) (4+а)

Answer 2

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

Step 1: Simplify the expression inside the parentheses. a² + 16a + 4 - a + 4a + a²(4 - a)²

Step 2: Expand the squared term. a² + 16a + 4 - a + 4a + a²(16 - 8a + a²)

Step 3: Distribute a² to the terms inside the parentheses. a² + 16a + 4 - a + 4a + 16a² - 8a³ + a⁴

Step 4: Combine like terms. a⁴ - 8a³ + 17a² + 19a + 4

Therefore, the simplified expression is a⁴ - 8a³ + 17a² + 19a + 4.
