They are: -5 and 4
the numbers are positive 5 and negative 4 5 x 4 = 20 5 + (-4) = 1 * * * * * WRONG! 5*(-4) = -20, NOT 20 The correct answer is the complex conjugate pair, 0.5 ± 4.444097*i where i is the imaginary square root of -1.
How about: 1*4*5 = 20

-4 x 5 = -20 and -4 + 5 = 1.

If you've written that correctly, there aren't two whole numbers that satisfy those conditions. -20 and -5 add to -25, but multiply to 100. -25 and 4 multiply to -100, but add to -21.
-5 and -15 because -5 + -15 equals -5 - 15 which is -20 and -5 multiplied by -15 = 75 (two negatives multiply to make a positive)

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

You can multiply 1 and 20, 2 and 10, 4 and 5.
