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