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 two numbers that equal one when added and negative six when multiplied are 3 and -2. When you add them together (3 + (-2)), you get 1. When you multiply them (3 * -2), you get -6.
