Check work and help please ! Find all numbers c that satisfy the conclusion of Rolle's Theorem for the following function and interval. f(x)=9x³ - 27x² + 18x + 10 , [0,2] f'(x)=27x² - 54x+18 I know I have to use f(b)-f(a)/ b-a so 9(2)³-27(2)²+18(2)+10 - (10) / 2-0 but I get 0/2 = 0 27x² - 54x+18= 0 ? and I end up getting 3 ± √3 / 3 ??
