What two numbers multiply to -709 and add up to 708?

Here we answer the question: "What two numbers multiply to -709 and add up to 708?"

The answer to your question is:

-1 and 709

Below we illustrate and prove that -1 and 709 multiply to -709 and add up to 708:

-1 × 709 = -709
-1 + 709 = 708

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

x² + 708x - 709 = 0

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

(x - 1 ) (x + 709)

To summarize, since -1 and 709 multiply to -709 and add up 708, you know that the following is true:

x² + 708x - 709 = (x - 1 ) (x + 709)
