What two numbers multiply to -630 and add up to 207?

Here we answer the question: "What two numbers multiply to -630 and add up to 207?"

The answer to your question is:

-3 and 210

Below we illustrate and prove that -3 and 210 multiply to -630 and add up to 207:

-3 × 210 = -630
-3 + 210 = 207

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

x² + 207x - 630 = 0

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

(x - 3 ) (x + 210)

To summarize, since -3 and 210 multiply to -630 and add up 207, you know that the following is true:

x² + 207x - 630 = (x - 3 ) (x + 210)
