Answer
\(-4(2x + 5)\)
Solution
To factor the expression \(-8x - 20\), follow these steps:
1. **Identify the Greatest Common Factor (GCF):**
- The coefficients are \(-8\) and \(-20\).
- The GCF of 8 and 20 is 4.
- Since both terms are negative, factoring out \(-4\) is appropriate to keep the expression simplified.
2. **Factor out the GCF:**
\[
-8x - 20 = -4(2x + 5)
\]
**Final Factored Form:**
\[
-4(2x + 5)
\]
