Question

What 2 numbers multiply to make -20 and add together to make 1?

Answer 1

5 and -4

Explanation:

We can start by determining the factors of -20, which are (1 * -20), (2 * -10), (4 * -5), (5 * -4), (10 * -2), and (20 * -1).

Since 5 * -4 = -20 and 5 + (-4) = 1, these are the two numbers.
