Let x and y be the two numbers. We can set up a system of equations: x + y = 20 and xy = 64. By solving the first equation for y (y = 20 - x) and substituting into the second equation, we get x(20 - x) = 64. Simplifying this quadratic equation gives us x^2 - 20x + 64 = 0. Factoring this equation gives us (x - 16)(x - 4) = 0. Therefore, the two numbers are 16 and 4.

The numbers are: -1 and -20
The two numbers that add to -8 and multiply to -20 are -10 and 2. This is because -10 + 2 = -8 and -10 * 2 = -20. These numbers satisfy both conditions simultaneously.
