What two numbers multiply to 670 and add up to -671?

Here we answer the question: "What two numbers multiply to 670 and add up to -671?"

The answer to your question is:

-670 and -1

Below we illustrate and prove that -670 and -1 multiply to 670 and add up to -671:

-670 × -1 = 670
-670 + -1 = -671

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

x² - 671x + 670 = 0

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

(x - 670 ) (x - 1)

To summarize, since -670 and -1 multiply to 670 and add up -671, you know that the following is true:

x² - 671x + 670 = (x - 670 ) (x - 1)
