Here we answer the question: "What two numbers multiply to -591 and add up to 590?"

The answer to your question is:

-1 and 591

Below we illustrate and prove that -1 and 591 multiply to -591 and add up to 590:

-1 × 591 = -591
-1 + 591 = 590

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

x² + 590x - 591 = 0
