Find the solution set of the inequation < 0. x ≠ 2
means we have to find values of x for which
is negative
Observe that the numerator |x – 2| is always positive because of mod, hence for to be a negative quantity the denominator (x – 2) has to be negative
That is x – 2 should be less than 0
⇒ x – 2 < 0
⇒ x < 2
Hence x should be less than 2 for
x < 2 means x can take values from -∞ to 2 hence x ∈ (-∞, 2)
Hence the solution set for is (-∞, 2)
