What two numbers multiply to -715 and add up to 714?

Here we answer the question: "What two numbers multiply to -715 and add up to 714?"

The answer to your question is:

-1 and 715

Below we illustrate and prove that -1 and 715 multiply to -715 and add up to 714:

-1 × 715 = -715
-1 + 715 = 714

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

x² + 714x - 715 = 0

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

(x - 1 ) (x + 715)

To summarize, since -1 and 715 multiply to -715 and add up 714, you know that the following is true:

x² + 714x - 715 = (x - 1 ) (x + 715)
