Because you deal with fractions you need to exclude from domain (possible answers) those values that will give you denominators equal to zero.
or or
So for the interval [,] we cannot have as solutions 0, , or .
Now as you do with any proportion, multiply on diagonal (butterfly method):
So this relation is true for every allowed value in the interval.
