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:

1 and 512

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

1 × 512 = 512
1 + 512 = 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 + 1 ) (x + 512)

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

x² + 513x + 512 = (x + 1 ) (x + 512)
