Does the order of a solution set in the quadratic equation matter?

Does the order matter for the solution set when solving a quadratic equation? For example, say my solution set was X = +8 or X = -2. I ask because when I look at the back of the book it shows me the correct answer in the reverse order (X=-2 and X =+8)...

The order of the solutions in the listing should not matter. Commonly, solution values are listed in "order"; in this case, -2 is less than +8, so the negative solution is listed before the positive one. But either way is mathematically valid. ;)
