Here we answer the question: "What two numbers multiply to -529 and add up to 0?"

The answer to your question is:

-23 and 23

Below we illustrate and prove that -23 and 23 multiply to -529 and add up to 0:

-23 × 23 = -529
-23 + 23 = 0

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

x² + 0x - 529 = 0

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

(x - 23 ) (x + 23)

To summarize, since -23 and 23 multiply to -529 and add up 0, you know that the following is true:

x² + 0x - 529 = (x - 23 ) (x + 23)
