How do you factor 4x+2y-18Z

Since the only thing common is the coefficients, it looks like you can factor a 2 out of each:

2 (2x + y -9z).

Hi, Kristine.

This polynomial has a GCF (Greatest Common Factor) of 2. The only thing you can do with this one is to rewrite it with a 2 in front of a grouping like this:

2( )

And then get the numbers inside the grouping by dividing each term of the original expression by the GCF (polynomial terms ÷ GCF)...

4x + 2y - 18z

2 2 2

2(2x + y - 9z)

... and that's it!
