In case somebody misses it, the reason he can discard 3x=10 is because if you put x=10/3 in x^2-2x-3 it will give you a fraction (only the constant term that does not have an x is a multiple of 3) and for it to work you need it to be 2

In this type exercises be aware of indeterminate forms, for example, if x=-1 was a solution of the base polynomial it wouldn't be a solution of the equation.

When 4 and 3 answer are
You have to x#11 /3

Hi. For the second case where you have that second degree equation how do you know how to factor it that easy? Is there some trick to it? If so, it'd be really appreciated. :)

for x = 10/3 there should be 9 solutions, all of which we know how to find. but conventionally there are zero.

you do realize that's stupid, right?
