Best ResponseYou've already chosen the best response.0you can divide both sides by 6x since they have that in common

Best ResponseYou've already chosen the best response.1What do you get if you divide both sides by any common factors?

Best ResponseYou've already chosen the best response.0this is what i got when i did the problem x=0, x=3 @whpalmer4 @Euler271

Best ResponseYou've already chosen the best response.1More more better: \[6x^2  18x = 0\]\[6x(x3) = 0\]\[6x = 0\]\[x3= 0\]

Best ResponseYou've already chosen the best response.0so the 3 is negitive?

Best ResponseYou've already chosen the best response.2No when solving x3=0 you would add 3 to both sides of the equal sign getting: x=3

Best ResponseYou've already chosen the best response.1One 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.
