Answer:

6(2x-5)

Explanation:

Find the Greatest Common Factor (GCF).

1 What is the largest number that divides evenly into 12x12x and -30−30?

It is 66.

2 What is the highest degree of xx that divides evenly into 12x12x and -30−30?

It is 1, since xx is not in every term.

3 Multiplying the results above,

The GCF is 66.

Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

6(\frac{12x}{6}-\frac{30}{6})
