What two numbers multiply to -630 and add up to -313?

Here we answer the question: "What two numbers multiply to -630 and add up to -313?"

The answer to your question is:

-315 and 2

Below we illustrate and prove that -315 and 2 multiply to -630 and add up to -313:

-315 × 2 = -630
-315 + 2 = -313

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

x² - 313x - 630 = 0

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

(x - 315 ) (x + 2)

To summarize, since -315 and 2 multiply to -630 and add up -313, you know that the following is true:

x² - 313x - 630 = (x - 315 ) (x + 2)
