[ 1/1Inequality]
Assignment:Find the solution set of inequality (2x^2-3x+1)/(3x^2-7x+2) >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 2 * x ^ 2 - 3 * x + 1 ) / ( 3 * x ^ 2 - 7 * x + 2 ) >0 (1)
From the definition field of divisor
3 * x ^ 2 - 7 * x + 2 ≠ 0 (2 )
From inequality(1):
x < 0.333333 或 1/2 < x < 1 或 x > 2
From inequality(2):
x < 1/3 或 1/3 < x < 2 或 x > 2
From inequalities (1) and (2)
x < 0.333333 或 1/2 < x < 1 或 x > 2 (3)
The final solution set is :
x < 0.333333 或 1/2 < x < 1 或 x > 2Your problem has not been solved here? Please take a look at the hot problems !
