if -c is over b-c then do the two c's cancel or sumthin?


so it stays the same?

I assume it stays the same. You don't say what you are trying to do. But

(-c)/(b-c) can't be reduced. It can be changed around some but the cs can't be canceled.

To determine if the two "-c" terms cancel when they are added to "b-c," we can simplify the expression by combining like terms.

Given the expression: "-c + b - c"

To combine the "-c" terms, you can rewrite the expression as:

"-2c + b"

This means that the two "-c" terms do not cancel each other out. Instead, they are combined to give us "-2c" in the simplified expression.
