What two numbers multiply to -477 and add up to 476?

Here we answer the question: "What two numbers multiply to -477 and add up to 476?"

The answer to your question is:

-1 and 477

Below we illustrate and prove that -1 and 477 multiply to -477 and add up to 476:

-1 × 477 = -477
-1 + 477 = 476

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

x² + 476x - 477 = 0

If so, the solution to factor the quadratic equation above is:

(x - 1 ) (x + 477)

To summarize, since -1 and 477 multiply to -477 and add up 476, you know that the following is true:

x² + 476x - 477 = (x - 1 ) (x + 477)
