Final answer:

To find and correct the mistakes in the given expression, combine like terms and distribute the negative sign.

Step-by-step explanation:

To find and correct the mistakes in the given expression and then simplify it, we can follow these steps:

  1. Simplify the given expression by combining like terms.
  2. Distribute the negative sign to the terms inside the parentheses.
  3. Combine all like terms again.

Let's now work through the steps:

Step 1:

Simplify the given expression: (2x³ - 2x² + 5x - 1) - (8x³ - 10x² - 2x + 4) + (-6x³ - 8x² + 3x + 3)

Combine like terms:

2x³ - 2x³ + 8x³ = 8x³

-2x² - 10x² - 8x² = -20x²

5x - 2x - 3x = 0x = 0

-1 + 4 - 3 = 0 - 6 = -6

The simplified expression is: 8x³ - 20x² - 6
