First: (X+3)(x+3) foil it.
Then distribute the 3x among the values and combine like terms
X = -5
The goal of this problem is to solve for x.
To solve x in this problem you need to find a way to get it by itself on the left side, the way to do this is divide -5x by -5.
You then also have to do the same for the right side. This gives you -5.
The answer your looking for is 3x - 6
The slope is 16/0 which means it is undefined
