What two numbers multiply to 317 and add up to -318?

Here we answer the question: "What two numbers multiply to 317 and add up to -318?"

The answer to your question is:

-317 and -1

Below we illustrate and prove that -317 and -1 multiply to 317 and add up to -318:

-317 × -1 = 317
-317 + -1 = -318

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

x² - 318x + 317 = 0

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

(x - 317 ) (x - 1)

To summarize, since -317 and -1 multiply to 317 and add up -318, you know that the following is true:

x² - 318x + 317 = (x - 317 ) (x - 1)
