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)

The numbers that multiply to 294 and add to 7 are 14 and -21. When you multiply 14 and -21, you get 294 (14 * -21 = -294). When you add them together, 14 + (-21) equals 7 (14 - 21 = -7).

The two numbers that add to get negative 36 and multiply to get negative 144 are -48 and 12. When you add them, -48 + 12 equals -36, and when you multiply them, -48 × 12 equals -144.
There are no two real numbers that do, but the complex numbers (2 + i) and (2 - i) will.If you want two numbers that multiply to negative 5 and add to positive 4 then: -1 and 5If you want two numbers that multiply to negative 5 and add to negative 4 then: 1 and -5
The numbers that multiply to 945 and add to negative 48 are -27 and -35. When you multiply them, (-27 \times -35 = 945), and when you add them, (-27 + (-35) = -48). Thus, these two numbers meet the required conditions.
The numbers are: 11+ square root of 415 and 11 - square root of 415
