I assume you mean this:
Code:
x 2
------ - -------
3x - 6 2 - x
Remove a common factor of 3 from the terms of the first denominator, and a common factor of -1 from the terms of the second denominator:
x 2
------ - ------
3(x - 2) -1(x - 2)
You can divide both numerator and denominator of the second fraction by -1:
x -2
------- - ---------
3(x - 2) (x - 2)
Now, find a common denominator. Rewrite the second fraction so that it has the common denominator. Subtract the numerators, and put the result over the common denominator.tbryant said:Ok, so if I understood you right the answer would be
x+2
------
3 (x-2)
Perhaps you missed the part about a common denominator. You can't add or subtract the numerators until the denominators are the same. Hint: the common denominator for these fractions is 3(x - 2). You'll need to rewrite the second fraction as an equivalent fraction with 3(x - 2) as its denominator.
