There are no two real numbers that do, but two complex numbers do: (3.5 + i 3.5 √23) and (3.5 - i 3.5 √23) If you want them to add to 7 and multiply to -294, then the two real numbers -14 and 21 work. Or if you want them to add to -7 and multiply to -294, then the two real numbers 14 and -21 work. To add to -7 and multiply to 294, the following two complex numbers work: (-3.5 + i 3.5 √23) and (-3.5 - i 3.5 √23)
3 x 23 = 69.

The two numbers you can multiply together to equal 782 are 23 by 34.
The two numbers you multiply together to equal 391 are 17 by 23.
There aren't any whole numbers that satisfy these conditions. The only numbers that multiply to 23 are 23 and 1.
They are: 1*23 = 23 that multiply to 23
