Question

factor: -12n - 20 -4(3n - 5) -4(3n + 5) 4(3n - 5) 4(3n + 5)

Explanation:

Step1: Find GCF of -12n and -20

The greatest common factor (GCF) of -12 and -20 is -4.

Step2: Factor out -4

Divide each term in \(-12n - 20\) by -4: \(\frac{-12n}{-4}+\frac{-20}{-4}=3n + 5\).
So, \(-12n - 20=-4(3n + 5)\).

Answer:

-4(3n + 5)
