Here we answer the question: "What two numbers multiply to -19 and add up to -18?"

The answer to your question is:

-19 and 1

Below we illustrate and prove that -19 and 1 multiply to -19 and add up to -18:

-19 × 1 = -19
-19 + 1 = -18

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

x² - 18x - 19 = 0

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

(x - 19 ) (x + 1)

To summarize, since -19 and 1 multiply to -19 and add up -18, you know that the following is true:

x² - 18x - 19 = (x - 19 ) (x + 1)
