Identify

(3x³ - 2x² + 4x - 8) - (5x³ + 12x² - 3x - 4)

Step 2: Simplify

[Distributive Property] Distribute negative: 3x³ - 2x² + 4x - 8 - 5x³ - 12x² + 3x + 4
Combine like terms (x³): -2x³ - 2x² + 4x - 8 - 12x² + 3x + 4
Combine like terms (x²): -2x³ - 14x² + 4x - 8 + 3x + 4
Combine like terms (x): -2x³ - 14x² + 7x - 8 + 4
Combine like terms: -2x³ - 14x² + 7x - 4
