Объяснение:

Answer 2

To simplify the expression 4x^2 - 2x - 3(x - 3)(x + 3), we can follow these steps:

1. Distribute the -3 to the terms inside the parentheses: 4x^2 - 2x - 3(x^2 - 3x + 3x - 9)

2. Combine like terms: 4x^2 - 2x - 3(x^2 - 9)

3. Distribute the -3 to the terms inside the second set of parentheses: 4x^2 - 2x - 3x^2 + 27

4. Combine like terms: (4x^2 - 3x^2) + (-2x + 27) x^2 - 2x + 27

So, the simplified expression is x^2 - 2x + 27.
