Here we answer the question: "What two numbers multiply to -910 and add up to -909?"

The answer to your question is:

-910 and 1

Below we illustrate and prove that -910 and 1 multiply to -910 and add up to -909:

-910 × 1 = -910
-910 + 1 = -909

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

x² - 909x - 910 = 0
