What two numbers multiply to -711 and add up to 710?

Here we answer the question: "What two numbers multiply to -711 and add up to 710?"

The answer to your question is:

-1 and 711

Below we illustrate and prove that -1 and 711 multiply to -711 and add up to 710:

-1 × 711 = -711
-1 + 711 = 710

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

x² + 710x - 711 = 0

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

(x - 1 ) (x + 711)

To summarize, since -1 and 711 multiply to -711 and add up 710, you know that the following is true:

x² + 710x - 711 = (x - 1 ) (x + 711)
