What two numbers multiply to -20 and add up to -19?

Here we answer the question: "What two numbers multiply to -20 and add up to -19?"

The answer to your question is:

-20 and 1

Below we illustrate and prove that -20 and 1 multiply to -20 and add up to -19:

-20 × 1 = -20
-20 + 1 = -19

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² - 19x - 20 = 0

If so, the solution to factor the quadratic equation above is:

(x - 20 ) (x + 1)

To summarize, since -20 and 1 multiply to -20 and add up -19, you know that the following is true:

x² - 19x - 20 = (x - 20 ) (x + 1)
