3-2x\geq 0 x-1<0
For the quotient to be ≤0, one of the values 3-2x and x-1 has to be ≥0, the other has to be ≤0, and x-1 cannot be zero. Consider the case when 3-2x\geq 0 and x-1 is negative.
x<1
Ikkala tengsizlikning mos yechimi – x<1.
3-2x\leq 0 x-1>0
Consider the case when 3-2x\leq 0 and x-1 is positive.
x\geq \frac{3}{2}
Ikkala tengsizlikning mos yechimi – x\geq \frac{3}{2}.
x<1\text{; }x\geq \frac{3}{2}
Oxirgi yechim olingan yechimlarning birlashmasidir.
