What two numbers multiply to -716 and add up to 715?

Here we answer the question: "What two numbers multiply to -716 and add up to 715?"

The answer to your question is:

-1 and 716

Below we illustrate and prove that -1 and 716 multiply to -716 and add up to 715:

-1 × 716 = -716
-1 + 716 = 715

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

x² + 715x - 716 = 0

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

(x - 1 ) (x + 716)

To summarize, since -1 and 716 multiply to -716 and add up 715, you know that the following is true:

x² + 715x - 716 = (x - 1 ) (x + 716)
