[ 1/1Inequality]
Assignment:Find the solution set of inequality (1014.52+593.79*x+212.89*x^2+11.5*x^3)/(2820.83+661.7312*x+12.74*x^2+x^3*23/18) >1.2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 1014.52 + 593.79 * x + 212.89 * x ^ 2 + 11.5 * x ^ 3 ) / ( 2820.83 + 661.7312 * x + 12.74 * x ^ 2 + x ^ 3 * 23 / 18 ) >1.2 (1)
From the definition field of divisor
2820.83 + 661.7312 * x + 12.74 * x ^ 2 + x ^ 3 * 23 / 18 ≠ 0 (2 )
From inequality(1):
x < -20.238564 或 -4.475323 < x < -3.22815 或 x > 3.640426
From inequality(2):
x < -4.475323 或 x > -4.475323
From inequalities (1) and (2)
x < -20.238564 或 -4.475323 < x < -3.22815 或 x > 3.640426 (3)
The final solution set is :
x < -20.238564 或 -4.475323 < x < -3.22815 或 x > 3.640426Your problem has not been solved here? Please take a look at the hot problems !
