The value that makes the denominators zero is \( x = 0 \).
Solución
To find the values of \( x \) that make the denominators zero in the equation
\[
\frac{3}{x} + 2 = \frac{5}{4x} + \frac{17}{8},
\]
we need to identify the denominators in the equation. The denominators are \( x \) and \( 4x \).
1. **Set the denominators to zero:**
- For \( x \):
\[
x = 0
\]
- For \( 4x \):
\[
4x = 0 \implies x = 0
\]
Both denominators yield the same value, \( x = 0 \).
Thus, the value that makes the denominators zero is:
\[
x = 0
\]
The provided answer \( x = \frac{21}{44} \) does not make the denominators zero. Therefore, the only value that makes the denominators zero is:
\[
\boxed{0}
\]

The Deep Dive
To determine when the denominators become zero, we need to examine each part of the equation. The denominators in question are \( x \) and \( 4x \). For \( x \), the denominator equals zero when \( x = 0 \). For \( 4x \), it also equals zero at \( x = 0 \). So, the value that makes the denominators zero is simply \( x = 0 \). Thus, the answer is: \( x = 0 \).
