Answer 2

To simplify the given expression (у-4)(у+3)+(у+1)²-(7-у)(7+у), follow these steps:

1. Expand each term within parentheses: (у-4)(у+3) = у² + 3у - 4у - 12 (у+1)² = у² + 2у + 1 (7-у)(7+у) = 49 - у²

2. Combine like terms within the expression: у² + 3у - 4у - 12 + у² + 2у + 1 - (49 - у²)

3. Group like terms together: (у² + у² - у²) + (3у - 4у + 2у) + (1 - 12 - 49)

4. Simplify each group of like terms: 0у² - (3у - 4у + 2у) - (12 + 1 - 49)

5. Continue simplifying: 0у² - (-1у) - (-36)

6. Further simplify the expression: у + 36

So, the simplified expression is у + 36.
