The product of two negative integers is positive. (-a) *(-b) = ab True
The product of two integers with different signs is positive. (-a) (b) = -ab False
If two numbers are the same sign, then the product is positive.
a*b = ab -a * -b = ab True
The product of a positive and a negative is negative.
-a * b =- ab a * -b =- ab True
If the signs of two integers are different, then the product is positive.
-a * b =- ab a * -b =- ab False

Expanding the left side gives
which gives two solutions,
and
. But if
, then
, but this number isn't real, so
is an extraneous solution. Meanwhile if
, you get
, so this solution is correct.
"Potential solutions" might refer to both possibilities, but there is only one actual (real) solution.
