What two numbers multiply to -522 and add up to 521?

Here we answer the question: "What two numbers multiply to -522 and add up to 521?"

The answer to your question is:

-1 and 522

Below we illustrate and prove that -1 and 522 multiply to -522 and add up to 521:

-1 × 522 = -522
-1 + 522 = 521

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

x² + 521x - 522 = 0

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

(x - 1 ) (x + 522)

To summarize, since -1 and 522 multiply to -522 and add up 521, you know that the following is true:

x² + 521x - 522 = (x - 1 ) (x + 522)
