What two numbers multiply to -630 and add up to -83?

Here we answer the question: "What two numbers multiply to -630 and add up to -83?"

The answer to your question is:

-90 and 7

Below we illustrate and prove that -90 and 7 multiply to -630 and add up to -83:

-90 × 7 = -630
-90 + 7 = -83

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

x² - 83x - 630 = 0

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

(x - 90 ) (x + 7)

To summarize, since -90 and 7 multiply to -630 and add up -83, you know that the following is true:

x² - 83x - 630 = (x - 90 ) (x + 7)
