factor 30y+18z

To factor 30y+18z, you need to find the greatest common factor (GCF) of the terms 30y and 18z.

The GCF of 30y and 18z is 6, since 6 is the largest number that divides both 30 and 18 evenly.

You can then factor out the GCF from each term to get:

30y + 18z
= 6 * (5y + 3z)

Therefore, the factored form of 30y + 18z is 6(5y + 3z).
