What two numbers multiply to -630 and add up to 629?

Here we answer the question: "What two numbers multiply to -630 and add up to 629?"

The answer to your question is:

-1 and 630

Below we illustrate and prove that -1 and 630 multiply to -630 and add up to 629:

-1 × 630 = -630
-1 + 630 = 629

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

x² + 629x - 630 = 0

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

(x - 1 ) (x + 630)

To summarize, since -1 and 630 multiply to -630 and add up 629, you know that the following is true:

x² + 629x - 630 = (x - 1 ) (x + 630)
