Question
Solution
We are solving the inequality: 
Set numerator and denominator equal to zero: ·        x – 1=0 ⇒ x= 1 ·        x+2=0 ⇒ x=−2 These divide the number line into intervals: ·        (−∞,−2) ·        (−2,1) ·        (1,∞) Test sign of expression in each interval Interval 1: (−∞,−2) Pick x=−3: 
Handle boundary points ·        x =−2 : Denominator becomes 0 → undefined → exclude ·        x = 1: Numerator becomes 0 → expression = 0 → not less than 0 → exclude The final answer is x ∈ (−2,1)
