2. (4x6+21x5 - 26x3+28x-10)+(x+5)
Answer (1)
Answer:here po I hope it helpsStep-by-step explanation:1. Combine like terms within the first set of parentheses: - Constant terms: -10- x terms: 28x- x² terms: 21x² - 26x³- x⁴ terms: 4x⁴ 2. Rewrite the expression with combined terms: (4x⁴ + 21x² - 26x³ + 28x - 10) + (x + 5) 3. Remove the parentheses (since there's a plus sign in front of them): 4x⁴ + 21x² - 26x³ + 28x - 10 + x + 5 4. Combine like terms again: - Constant terms: -10 + 5 = -5- x terms: 28x + x = 29x 5. Write the final simplified expression: 4x⁴ - 26x³ + 21x² + 29x - 5
