What two numbers multiply to -617 and add up to 616?

Here we answer the question: "What two numbers multiply to -617 and add up to 616?"

The answer to your question is:

-1 and 617

Below we illustrate and prove that -1 and 617 multiply to -617 and add up to 616:

-1 × 617 = -617
-1 + 617 = 616

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

x² + 616x - 617 = 0

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

(x - 1 ) (x + 617)

To summarize, since -1 and 617 multiply to -617 and add up 616, you know that the following is true:

x² + 616x - 617 = (x - 1 ) (x + 617)
