-- If you accept decimals and fractions, then there are an infinite number of pairs that
satisfy that description.
-- If you only want to consider whole numbers, then there are only two possible pairs:
1 and 13
-1 and -13
If the sum of 2 numbers is 25 and their product is 156, the 2 numbers would be 12 and 13.
The two numbers that have a product of -26 and a sum of -11 are -13 and 2. When multiplied, -13 × 2 equals -26, and when added, -13 + 2 equals -11.
156 = 2 * 2 * 3 *13
7*13*2*2
9 x 13 = 117
9 and 13
12 and 13.
As a product of its prime factors: 2*3*13 = 78
1, 3 The above solution is wrong! 1+3=4 ok. But what about product? 1x3 = 3 and not 13. So the answer is wrong. The right answer is 2+3i and 2-3i. Of course the numbers are not real numbers but they are complex.

3 and 13
The numbers are 13 and 14.
