What two numbers multiply to -999 and add up to -10?

Here we answer the question: "What two numbers multiply to -999 and add up to -10?"

The answer to your question is:

-37 and 27

Below we illustrate and prove that -37 and 27 multiply to -999 and add up to -10:

-37 × 27 = -999
-37 + 27 = -10

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

x² - 10x - 999 = 0

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

(x - 37 ) (x + 27)

To summarize, since -37 and 27 multiply to -999 and add up -10, you know that the following is true:

x² - 10x - 999 = (x - 37 ) (x + 27)
