It looks like there is an issue with the expression you provided, as it seems incomplete or not properly formatted.

Let me try to rewrite it based on what I can infer:

$\frac{189(x-1)(x+5)(x+9)}{63x^2 + 12x - 15}$

This could be the intended expression, but if it differs from what you meant, feel free to clarify. Here's what can be done next:

Steps to analyze this expression:

1. Factor the numerator and the denominator (if possible): This helps simplify the expression.
2. Check for any common factors: Cancel out terms that appear both in the numerator and the denominator.
3. Analyze the simplified form: If the terms are reduced, rewrite the final expression.

Would you like me to continue with this assumed expression, or can you clarify any part that needs adjusting?

Let me know if you'd like more details on any step.
