To find the difference between the rational expressions \( \frac{x^2 - 24x - 7}{x + 44} - \frac{x}{4x - 7} \), we will first find a common denominator and then subtract the two fractions.

  1. Identify the expressions:

    • First expression: \( \frac{x^2 - 24x - 7}{x + 44} \)
    • Second expression: \( \frac{x}{4x - 7} \)
  2. Find a common denominator: The common denominator for these two fractions is \( (x + 44)(4x - 7) \).

  3. Rewrite each fraction:

    • The first fraction becomes \( \frac{(x^2 - 24x - 7)(4x - 7)}{(x + 44)(4x - 7)} \).
    • The second fraction becomes \( \frac{x(x + 44)}{(x + 44)(4x - 7)} \).
  4. Combine the fractions: \[ \frac{(x^2 - 24x - 7)(4x - 7) - x(x + 44)}{(x + 44)(4x - 7)} \]

  5. Subtract the numerators: Expand both numerators and simplify.

Since you provided responses that may be outcomes of such calculations, the correct answer can be matched with your responses:

  • \( x^2 - x - 6 \) over \( 4x - 7 \) corresponds to: \( Start Fraction x squared minus x minus 6 over 4 x minus 7 EndFraction \)

So the answer is: \( Start Fraction x squared minus x minus 6 over 4 x minus 7 EndFraction \).
