Here we answer the question: "What two numbers multiply to 671 and add up to -672?"

The answer to your question is:

-671 and -1

Below we illustrate and prove that -671 and -1 multiply to 671 and add up to -672:

-671 × -1 = 671
-671 + -1 = -672

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

x² - 672x + 671 = 0

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

(x - 671 ) (x - 1)

To summarize, since -671 and -1 multiply to 671 and add up -672, you know that the following is true:

x² - 672x + 671 = (x - 671 ) (x - 1)
