Here we answer the question: "What two numbers multiply to 617 and add up to -618?"

The answer to your question is:

-617 and -1

Below we illustrate and prove that -617 and -1 multiply to 617 and add up to -618:

-617 × -1 = 617
-617 + -1 = -618

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

x² - 618x + 617 = 0

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

(x - 617 ) (x - 1)

To summarize, since -617 and -1 multiply to 617 and add up -618, you know that the following is true:

x² - 618x + 617 = (x - 617 ) (x - 1)
