No two real numbers, but the complex numbers:

7/2 + i(√7)/2 and 7/2 - i(√7)/2

Multiplying to negative 14 and adding to 7 the two numbers:

(7 + √105)/2 (≈ 8.623) and (7 - √105)/2 (≈ -1.623)

What adds to 7 and multiples to 294?

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)
