Here we answer the question: "What two numbers multiply to 628 and add up to -629?"

The answer to your question is:

-628 and -1

Below we illustrate and prove that -628 and -1 multiply to 628 and add up to -629:

-628 × -1 = 628
-628 + -1 = -629

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

x² - 629x + 628 = 0

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

(x - 628 ) (x - 1)

To summarize, since -628 and -1 multiply to 628 and add up -629, you know that the following is true:

x² - 629x + 628 = (x - 628 ) (x - 1)
