(3 + 2u - 2u^10 + u^11 - 3u²)- ( -u^10 + 6u² - u - 2)

(3 + 2u - 2u^10 + u^11 - 3u²) + u^10 - 6u² + u + 2

3 + 2u - 2u^10 + u^11 - 3u² + u^10 - 6u² + u + 2 (combine like terms)

u^11 - u^10 - 9u² + 3u + 5 -this is the final answer

U¹¹ -u¹⁰-9u²+3u+5

Step-by-step explanation:

What their is a - in front of an expression in parenthesis change the sign of each term in the expression
