you can divide both sides by 6x since they have that in common

What do you get if you divide both sides by any common factors?

Are you sure about the sign in x=3

More more better: \[6x^2  18x = 0\]\[6x(x3) = 0\]\[6x = 0\]\[x3= 0\]

so the 3 is negitive?

No when solving x3=0 you would add 3 to both sides of the equal sign getting: x=3

One thing that we haven't exactly made clear here: if you did just divide both sides by 6x as suggested at first: \[6x^2 = 18x\]\[x=3\]You might get the impression that your work is done. However, there's an important thing to know, which is if your polynomial has \(x^n\) as its highest power, you must have \(n\) solutions! Some of them may be identical, but you will have that many. That would be a clue here that \(x=3\) isn't the entire story.
