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)

7, 14, 21 and just keep adding 7 until you get to 294.
Prime decomposition of 294: 294 = 2 x 3 x 7^2 Other ways of writing 294: 294 = 1 x 294 294 = 2 x 147 294 = 3 x 98 294 = 6 x 49 294 = 7 x 42 294 = 14 x 21

The factor pairs of 294 are (294, 1) (147, 2) (98, 3) (49, 6) (42, 7) (21, 14) None of them add up to 7. If that was -294, you could use 21 and -14

There are infinitely many of them so they cannot be listed. One of their multiples is 294*252*210 = 15558480.
5 multiples of 98 are: 98, 196, 294, 392, and 490.
98, 196, 294, 392, 490, 588, 686, 784, 882, 980, 1078, 1176.
