What does the X mean?
ScaryPerson:
The x just represents a variable. If it is alone then it represents a 1
ScaryPerson:
when i say alone i mean this:
Joe348:
oh okay i get it
TETSXPREME:
but what if its with a number?

ScaryPerson:
2x- this isn't alone becaus there is a number in front of the x
Joe348:
so we just leave it alone?
ScaryPerson:
x- this is alone which means it should represent 1
ScaryPerson:
Yes. unless there are more to add by
ScaryPerson:
if there isn't anymore to add by then leave it alone

ScaryPerson:
what about it?
TETSXPREME:
what if its like 8x?
ScaryPerson:
if its 8x and there isn't any other x's to add or subtract then you leave it.
ScaryPerson:
but if its like our problem...
ScaryPerson:
then we would add 1 to it and square 2

ScaryPerson:
so it would look like this
ScaryPerson:
\[9x ^{2}\]
TETSXPREME:
then i do?
ScaryPerson:
that is it
ScaryPerson:
unless the directions says to solve it anymore than that, you should leave it alone
