Answer:Let's simplify the given expressions:
(5x^2 - 17x - 15) + (x - 4)
= 5x^2 - 17x - 15 + x - 4
= 5x^2 - 16x - 19
(6x³ - 16x² + 17x - 6) + (3x - 2)
= 6x³ - 16x² + 17x - 6 + 3x - 2
= 6x³ - 16x² + 20x - 8
(2x^4 + x³ - 19x² + 18x + 5) + (2x - 5)
= 2x^4 + x³ - 19x² + 18x + 5 + 2x - 5
= 2x^4 + x³ - 19x² + 20x
(4x^5 + 6x^4 + 5x² - x - 10) + (2x² + 3)
= 4x^5 + 6x^4 + 5x² - x - 10 + 2x² + 3
= 4x^5 + 6x^4 + 7x² - x - 7
(4x^5 - 25x + 40x³ + 3x² + 18x) + (x² - 6x + 9)
= 4x^5 - 25x + 40x³ + 3x² + 18x + x² - 6x + 9
= 4x^5 + 40x³ + 4x² - 25x + 18x - 6x + 9
= 4x^5 + 40x³ + 4x² - 13x + 9
