What two numbers multiply to -1000 and add up to -999?

Here we answer the question: "What two numbers multiply to -1000 and add up to -999?"

The answer to your question is:

-1000 and 1

Below we illustrate and prove that -1000 and 1 multiply to -1000 and add up to -999:

-1000 × 1 = -1000
-1000 + 1 = -999

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

x² - 999x - 1000 = 0

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

(x - 1000 ) (x + 1)

To summarize, since -1000 and 1 multiply to -1000 and add up -999, you know that the following is true:

x² - 999x - 1000 = (x - 1000 ) (x + 1)
