What two numbers multiply to 512 and add up to -513?

Here we answer the question: "What two numbers multiply to 512 and add up to -513?"

The answer to your question is:

-512 and -1

Below we illustrate and prove that -512 and -1 multiply to 512 and add up to -513:

-512 × -1 = 512
-512 + -1 = -513

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

x² - 513x + 512 = 0

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

(x - 512 ) (x - 1)

To summarize, since -512 and -1 multiply to 512 and add up -513, you know that the following is true:

x² - 513x + 512 = (x - 512 ) (x - 1)
