To find two numbers that add to 20 and multiply to 29, we can set up a system of equations. Let's call the two numbers x and y. We have the following equations: x + y = 20 and x * y = 29. By solving these equations simultaneously, we find that the two numbers are 5 and 15.
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.
