Assignment:Find the solution set of inequality 9x-5/(x-2)(x-3) ≥-2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
9 * x - 5 / ( x - 2 ) * ( x - 3 ) ≥ -2 (1)
From the definition field of divisor
x - 2 ≠ 0 (2 )
From inequality(1):
0.793989 ≤ x ≤ 1.539345 或 x ≥ 2
From inequality(2):
x < 2 或 x > 2
From inequalities (1) and (2)
0.793989 ≤ x ≤ 1.539345 或 x > 2 (3)
The final solution set is :
0.793989 ≤ x ≤ 1.539345 或 x > 2Your problem has not been solved here? Please take a look at the hot problems !
