Factors are multiplied, not added. The question needs to be something like, "Which two factors of thirty add up to 11?" The answer would then be 5 and 6.
X2 + 10X - 11 = 0What two factors of - 11 add up to 10 ?(X - 1)(X + 11)==========X = 1X = - 11

The factors are 1 & 11 !
It has two factors: 1 and 11.
When the "factors" of a number are listed, the list is usually restricted to positive factors. Then there would be no answer to the question, because no group of positive numbers can add up to make zero.
