Question
Write the solution of the inequation\[\frac{x^2}{x - 2} > 0\]
Solution
\[\text{ We have }, \]
\[\frac{x^2}{x - 2} > 0\]
\[\text{ Equating both the numerator and the denominator with zero, we obtain x = 0 and x = 2 as critical points } . \]
\[\text{ Plotting these points on the real line, we see that the real line is divided into three regions } .
\[\text{ Therefore, the solution set of the given inequality is } x \in (2, \infty )\]
