im not sure how to write it, when x = 2-, is this correct
The sign goes in front like this -2. That is negative 2.
]]>so would it be 2++1
so if I had (2-x)(1+x) and x = 2+ (instead of 2-)
it would be (2-+2) and (1++2)
is this correct, please could you point me in the right direction.
]]>I also have (1+x) and im not sure what to do with that either. can I just swap them like (x+1)
You can say ( x + 1 ) = ( 1 + x ). It does work for -2.
]]>im not sure if its
when x = 2-, or
when x = -2
it looks like (+2-x), it doesn't look like a minus. could it be that -x is treated as -1 so it becomes,
when x = +1 so it would be (2-+1) leaving just 1.
is this right im not sure.
I also have (1+x) and im not sure what to do with that either. can I just swap them like (x+1) that doesn't seem right though. after using 6 for x I get 7 either way. 1+6 or 6+1 but this doesn't work for the 2- as the answer would be the same just one would be minus the other positive. unless im completely confused on the matter......somethings cooking, smells like brain!!!
please help!!!
cheers
