Answer:
-1
Step-by-step explanation:
(x-3)/(3-x)
Reorder the terms in the denominator.
(x-3)/(-x + 3)
After, factor out the negative sign in order to cancel. Since we can cancel if the expression is divided by its opposite.
By doing this the sign within the parenthesis changes.
Put the negative sign outside the parenthesis. Then change signs.
(x-3)/- (x +3)
Since the expression is divided by its opposite we can cancel, this equals to 1 and with the negative, we have -1.
