[ 1/1Inequality]
Assignment:Find the solution set of inequality [(2x-5)(x+1)]/[(x+3)(x-2)] >3 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( ( 2 * x - 5 ) * ( x + 1 ) ) / ( ( x + 3 ) * ( x - 2 ) ) >3 (1)
From the definition field of divisor
( x + 3 ) * ( x - 2 ) ≠ 0 (2 )
From inequality(1):
-7.690416 < x < -3 或 1.690416 < x < 2
From inequality(2):
x < -3 或 -3 < x < 2 或 x > 2
From inequalities (1) and (2)
-7.690416 < x < -3 或 1.690416 < x < 2 (3)
The final solution set is :
-7.690416 < x < -3 或 1.690416 < x < 2 Your problem has not been solved here? Please take a look at the hot problems !
