Subtract: 3t⁴ - 4t³ + 2t² - 6t + 6 from - 4t⁴ + 8t³ - 4t² - 2t + 11
Solution:
Given, subtract 3t⁴ - 4t³ + 2t² - 6t + 6 from - 4t⁴ + 8t³ - 4t² - 2t + 11
⇒ (- 4t⁴ + 8t³ - 4t² - 2t + 11) - (3t⁴ - 4t³ + 2t² - 6t + 6)
= - 4t⁴ + 8t³ - 4t² - 2t + 11 - 3t⁴ + 4t³ - 2t² + 6t - 6)
= - 4t⁴ - 3t⁴ + 8t³ - (-4t³) - 4t² - 2t² - 2t + 6t + 11 - 6
= -7t⁴ + 12t³ - 6t² + 4t + 5
