What two numbers multiply to 721 and add up to -722?

Here we answer the question: "What two numbers multiply to 721 and add up to -722?"

The answer to your question is:

-721 and -1

Below we illustrate and prove that -721 and -1 multiply to 721 and add up to -722:

-721 × -1 = 721
-721 + -1 = -722

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

x² - 722x + 721 = 0

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

(x - 721 ) (x - 1)

To summarize, since -721 and -1 multiply to 721 and add up -722, you know that the following is true:

x² - 722x + 721 = (x - 721 ) (x - 1)
