Here we answer the question: "What two numbers multiply to -281 and add up to -280?"

The answer to your question is:

-281 and 1

Below we illustrate and prove that -281 and 1 multiply to -281 and add up to -280:

-281 × 1 = -281
-281 + 1 = -280

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

x² - 280x - 281 = 0
