Question
Evaluate (8x³ + 2x² - 4x + 2) - (-x⁴ + x² + 5x)
Correct Answer
Option C is the correct answer.
Detailed Explanation
(8x³ + 2x² - 4x + 2) - (-x⁴ + x² + 5x) = 8x³ + 2x² - 4x + 2 + x⁴ - x² - 5x = x⁴ + 8x³ + (2x² - x²) + (-4x - 5x) + 2 = x⁴ + 8x³ + x² - 9x + 2.
Hint
Distribute the negative sign and combine like terms.
