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

The answer to your question is:

-722 and 1

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

-722 × 1 = -722
-722 + 1 = -721

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

x² - 721x - 722 = 0
