No two real numbers do, but two complex numbers do: (2 + i√3) and (2 - i√3).
Multiplying to -7 and adding to 4 are the two numbers: (2 + √11) ≈ 5.317 and (2 - √11) ≈ -1.317
Multiplying to -7 and adding to -4 are the two numbers: (-2 + √11) ≈ 1.317 and (-2 - √11) ≈ -5.317
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
