Answer :
To solve the inequality [tex]\(\frac{x}{2x - 1} < 0\)[/tex], we should first understand when this expression is negative. The fraction is negative when the numerator and denominator have opposite signs. Here's how we can analyze it step-by-step:
1. Analyze the Numerator:
The numerator [tex]\(x\)[/tex] is zero when [tex]\(x = 0\)[/tex]. It is negative when [tex]\(x < 0\)[/tex].
2. Analyze the Denominator:
The denominator [tex]\(2x - 1\)[/tex] is zero when [tex]\(2x - 1 = 0\)[/tex], giving [tex]\(x = \frac{1}{2}\)[/tex]. It is negative when [tex]\(2x - 1 < 0\)[/tex], which simplifies to [tex]\(x < \frac{1}{2}\)[/tex].
3. Determine the Intervals:
- For the fraction to be negative, the signs of the numerator and denominator must be opposite. So, we have two situations where the fraction is negative:
- [tex]\(x < 0\)[/tex] and [tex]\(x < \frac{1}{2}\)[/tex]: Since both need to be true, the interval is [tex]\(x < 0\)[/tex].
- [tex]\(x > 0\)[/tex] and [tex]\(x > \frac{1}{2}\)[/tex]: This combination doesn't result in a solution because both intervals would imply positive values.
Thus, the effective interval for the solution is when these pieces work together properly in the negative region. Note this means we are focusing on [tex]\(x < 0\)[/tex].
4. Handle Points Where the Denominator or Numerator is Zero:
- Where [tex]\(x = 0\)[/tex], the fraction is zero, not negative.
- Where [tex]\(x = \frac{1}{2}\)[/tex], the denominator is zero, leading to an undefined expression.
5. Determine Valid Solution Intervals:
From our analysis, the valid interval where the inequality holds is [tex]\(-\infty < x < 0\)[/tex] and [tex]\(0 < x < \frac{1}{2}\)[/tex]. However, since the question specifies choices with a particular maximum range [tex]\(x < \frac{1}{2}\)[/tex], it leads us to consider this portion within reasonable domain values (same choice within scope of options given in question).
Putting it all together, the correct solution over the range considered in answer choices, from our detailed signs check in steps and problem framing, is:
- [tex]\(-4 < x < \frac{1}{2}\)[/tex]
None of the given options exactly describe both segments from negative to zero or zeros around critical points with exclusions this same way but the nearest relevant max expected definition holds for this choice in desired scope of options. Thus, the best answer choice based on aligning with the whole inequality response or description steps is:
- [tex]\(x < \frac{1}{2}\)[/tex] focusing from possibility and select keen intervals matching right logically [tex]\(x\)[/tex]. Thoughtfully encapsulate positive or negatives ensuring dependent on all constraints broadly generating intersections from parts possibly grounded poly.
