What two numbers multiply to -317 and add up to 316?

Here we answer the question: "What two numbers multiply to -317 and add up to 316?"

The answer to your question is:

-1 and 317

Below we illustrate and prove that -1 and 317 multiply to -317 and add up to 316:

-1 × 317 = -317
-1 + 317 = 316

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

x² + 316x - 317 = 0

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

(x - 1 ) (x + 317)

To summarize, since -1 and 317 multiply to -317 and add up 316, you know that the following is true:

x² + 316x - 317 = (x - 1 ) (x + 317)
