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:

-2 and 315

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

-2 × 315 = -630
-2 + 315 = 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 - 2 ) (x + 315)

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

x² + 313x - 630 = (x - 2 ) (x + 315)
