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:

-27 and 37

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

-27 × 37 = -999
-27 + 37 = 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 - 27 ) (x + 37)

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

x² + 10x - 999 = (x - 27 ) (x + 37)
