The only x quantities that can be canceled are factors. Many students mistakenly ‘‘can2þx 2þ1 2þx cel’’ the x and conclude that ¼ ¼ 3 or ¼ 2. These equations x 1 x 2þx are false. If were equal to 2 or to 3, then we could substitute any value x for x (except for 0) and we would get a true equation. Let’s try x = 19: 2 þ 19 21 ¼ . 19 19 2þx 2þx We can see that 6¼ 2 and 6¼ 3. The reason that the x cannot be x x factored is that x is a term in this expression, not a factor. ) If you must cancel 2þx the x out of , you must rewrite the fraction: x CHAPTER 2 Introduction to Variables 2þx 2 x 2 ¼ þ ¼ þ 1: x x x x Simply because a plus or minus sign appears in a fraction does not auto3þx matically mean that canceling is not appropriate.
