What two numbers multiply to -630 and add up to -99?

Here we answer the question: "What two numbers multiply to -630 and add up to -99?"

The answer to your question is:

-105 and 6

Below we illustrate and prove that -105 and 6 multiply to -630 and add up to -99:

-105 × 6 = -630
-105 + 6 = -99

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

x² - 99x - 630 = 0

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

(x - 105 ) (x + 6)

To summarize, since -105 and 6 multiply to -630 and add up -99, you know that the following is true:

x² - 99x - 630 = (x - 105 ) (x + 6)
