Answer 2

To simplify the expression 3x² - 9x - (8 - 5x² - (9x - 8x²)), you can start by distributing the negative sign to all the terms within the parentheses:

3x² - 9x - 8 + 5x² + 9x - 8x²

Now, you can combine like terms:

(3x² + 5x² - 8x²) + (-9x + 9x - 8)

Combine the x² terms:

(3x² + 5x² - 8x²) = 0x² = 0

Combine the x terms:

(-9x + 9x) = 0

Now, you're left with:

0 - 8 = -8

So, the simplified expression is -8.
