What two numbers multiply to -999 and add up to -102?

Here we answer the question: "What two numbers multiply to -999 and add up to -102?"

The answer to your question is:

-111 and 9

Below we illustrate and prove that -111 and 9 multiply to -999 and add up to -102:

-111 × 9 = -999
-111 + 9 = -102

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

x² - 102x - 999 = 0

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

(x - 111 ) (x + 9)

To summarize, since -111 and 9 multiply to -999 and add up -102, you know that the following is true:

x² - 102x - 999 = (x - 111 ) (x + 9)
