What two numbers multiply to -713 and add up to 8?

Here we answer the question: "What two numbers multiply to -713 and add up to 8?"

The answer to your question is:

-23 and 31

Below we illustrate and prove that -23 and 31 multiply to -713 and add up to 8:

-23 × 31 = -713
-23 + 31 = 8

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

x² + 8x - 713 = 0

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

(x - 23 ) (x + 31)

To summarize, since -23 and 31 multiply to -713 and add up 8, you know that the following is true:

x² + 8x - 713 = (x - 23 ) (x + 31)
