What two numbers multiply to 517 and add up to 518?

Here we answer the question: "What two numbers multiply to 517 and add up to 518?"

The answer to your question is:

1 and 517

Below we illustrate and prove that 1 and 517 multiply to 517 and add up to 518:

1 × 517 = 517
1 + 517 = 518

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

x² + 518x + 517 = 0

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

(x + 1 ) (x + 517)

To summarize, since 1 and 517 multiply to 517 and add up 518, you know that the following is true:

x² + 518x + 517 = (x + 1 ) (x + 517)
