Is order matter when writing the roots of a quadratic equation?

Question

Equation:

$x^2-x-6=0$

The two roots of this equation are $3$ and $-2$. When writing the answer can I also write it as $-2, 3$ or do I have to maintain a certain order?

Answer 1

If the question offers the two choices you gave us in a comment, $-2, 3$ and $3, -2$, then the question is wrong. Either answer is correct. Perhaps one of the suggested answers should have had the signs the other way $2, -3$ ( not the order the other way). Then they might be looking for a particular error you might have made.

Answer 2

The order of the roots should not matter, the solutions {-2,3} still conveys the same meaning as {3, -2}. Edit: some people may prefer you to order your solution from the least greatest to greatest value for ease of marking (e.g. -2 then 3), but mathematically, it makes no difference.
