What two numbers multiply to -316 and add up to 315?

Here we answer the question: "What two numbers multiply to -316 and add up to 315?"

The answer to your question is:

-1 and 316

Below we illustrate and prove that -1 and 316 multiply to -316 and add up to 315:

-1 × 316 = -316
-1 + 316 = 315

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

x² + 315x - 316 = 0

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

(x - 1 ) (x + 316)

To summarize, since -1 and 316 multiply to -316 and add up 315, you know that the following is true:

x² + 315x - 316 = (x - 1 ) (x + 316)
