Here we answer the question: "What two numbers multiply to -578 and add up to 577?"

The answer to your question is:

-1 and 578

Below we illustrate and prove that -1 and 578 multiply to -578 and add up to 577:

-1 × 578 = -578
-1 + 578 = 577

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

x² + 577x - 578 = 0
