When the sum of two whole numbers is multiplied by the difference of the numbers, the result is 85.
If the difference of the two numbers is not 1 what is the sum
(a+b)*(a-b) = 85
FOIL
a^2 - b^2 = 85
a^2 = b^2 + 85
a =
first integer solution

Let the larger and smaller WHOLE numbers be L and S
Then we get: (L + S)(L - S) = 85
85 has 2 SETS of factors, which are: 85 and 1, and 5 and 17
85 and 1 OBVIOUSLY can't be the larger and smaller WHOLE numbers
Therefore, L - S MUST = 5, and
