7 and 13.
Solution : Let the two numbers be a and b. Then ab = 91 , so b = 91/a.
a + b = 20 .......substituting for b, this becomes : a + (91/a) =20
Multiplying both sides by a gives : a2 + 91 = 20a
Rearranging : a2 - 20a + 91 = 0
Factoring gives : (a - 7)(a - 13) = 0
Then the numbers occur when x - 7 = 0. → x = 7, and when x - 13 = 0. → x = 13.
