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

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

The answer to your question is:

-1 and 318

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

-1 × 318 = -318
-1 + 318 = 317

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

x² + 317x - 318 = 0

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

(x - 1 ) (x + 318)

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

x² + 317x - 318 = (x - 1 ) (x + 318)
