What two numbers multiply to -529 and add up to 528?

Here we answer the question: "What two numbers multiply to -529 and add up to 528?"

The answer to your question is:

-1 and 529

Below we illustrate and prove that -1 and 529 multiply to -529 and add up to 528:

-1 × 529 = -529
-1 + 529 = 528

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

x² + 528x - 529 = 0

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

(x - 1 ) (x + 529)

To summarize, since -1 and 529 multiply to -529 and add up 528, you know that the following is true:

x² + 528x - 529 = (x - 1 ) (x + 529)
