To solve the given problem, we need to find the derivative of the function

\[
y = \left(\frac{-5x + 4}{-3x + 1}\right)^3
\]

### Step-by-Step Solution:

We are dealing with a composition of functions here, so we will apply the **chain rule** and **quotient rule**.

1. **Apply the chain rule**:
   \[
   \frac{dy}{dx} = 3 \left( \frac{-5x + 4}{-3x + 1} \right)^2 \cdot \frac{d}{dx}\left( \frac{-5x + 4}{-3x + 1} \right)
   \]
   So, we first take the derivative of the outer function and leave the inner function intact, multiplying by the derivative of the inner function (the quotient).

2. **Apply the quotient rule** for the inner derivative \( \frac{-5x + 4}{-3x + 1} \):

   The quotient rule states that for \( \frac{f(x)}{g(x)} \), the derivative is:
   \[
   \frac{d}{dx}\left( \frac{f(x)}{g(x)} \right) = \frac{f'(x)g(x) - f(x)g'(x)}{(g(x))^2}
   \]
   Here:
   - \( f(x) = -5x + 4 \) and \( g(x) = -3x + 1 \)
   - \( f'(x) = -5 \) and \( g'(x) = -3 \)

   Applying the quotient rule:
   \[
   \frac{d}{dx}\left( \frac{-5x + 4}{-3x + 1} \right) = \frac{(-5)(-3x + 1) - (-5x + 4)(-3)}{(-3x + 1)^2}
   \]
   Simplifying:
   \[
   = \frac{15x - 5 - (-15x + 12)}{(-3x + 1)^2}
   \]
   \[
   = \frac{15x - 5 + 15x - 12}{(-3x + 1)^2}
   \]
   \[
   = \frac{30x - 17}{(-3x + 1)^2}
   \]

3. **Combine everything**:
   Now substitute this back into the chain rule expression:
   \[
   \frac{dy}{dx} = 3 \left( \frac{-5x + 4}{-3x + 1} \right)^2 \cdot \frac{30x - 17}{(-3x + 1)^2}
   \]
   Simplifying:
   \[
   \frac{dy}{dx} = \frac{3(-5x + 4)^2 (30x - 17)}{(-3x + 1)^4}
   \]

So, the derivative of the given function in factored form is:

\[
\frac{dy}{dx} = \frac{3(-5x + 4)^2 (30x - 17)}{(-3x + 1)^4}
\]
