Assignment:Find the solution set of inequality N^6-(2*2-8)*N^5+(2^2+7*2+67/2)*N^4+(6*(2^2)-37/2*2-287/4)*N^3+(5*(2^2)-211/4*2+595/16)*N^2-(12*(2^2)-337/4*2+1793/16)*N+(4*(2^2)-55/2*2+5053/64) >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
N ^ 6 - ( 2 * 2 - 8 ) * N ^ 5 + ( 2 ^ 2 + 7 * 2 + 67 / 2 ) * N ^ 4 + ( 6 * ( 2 ^ 2 ) - 37 / 2 * 2 - 287 / 4 ) * N ^ 3 + ( 5 * ( 2 ^ 2 ) - 211 / 4 * 2 + 595 / 16 ) * N ^ 2 - ( 12 * ( 2 ^ 2 ) - 337 / 4 * 2 + 1793 / 16 ) * N + ( 4 * ( 2 ^ 2 ) - 55 / 2 * 2 + 5053 / 64 ) >0 (1)
From inequality(1):
N < 0.756866 或 N > 1.673602
The final solution set is :
N < 0.756866 或 N > 1.673602Your problem has not been solved here? Please take a look at the hot problems !
