Step 1: Group this into two groups:

When you do that, be sure to group the "–" into the group with the 9 and make sure there's "+" between the groups.
Step 2: Factor out the GCF from both individual groups:

Step 3: Notice both groups have that (h+2)? That's a new GCF between the two groups, so factor that out:

Step 4: That
piece can be factored further, since it's a difference of squares:

Now it's factored.
Answer:
A. 18x - 3y = 6
Step-by-step explanation:
By taking 3 common from the terms 18x and 3y we get,
3 (6x-3y) = 6
or, 6x - y = 6/3
or, 6x - y = 2
And,
The equation becomes,
y = 6x - 2
