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.
The two numbers that add to -11 and multiply to 19 are -10 and -1. When you add them together, -10 + (-1) equals -11. When you multiply them, -10 × -1 equals 10, not 19. Therefore, there are no two real numbers that satisfy both conditions simultaneously.
