What two numbers multiply to 510 and add up to 511?

Here we answer the question: "What two numbers multiply to 510 and add up to 511?"

The answer to your question is:

1 and 510

Below we illustrate and prove that 1 and 510 multiply to 510 and add up to 511:

1 × 510 = 510
1 + 510 = 511

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

x² + 511x + 510 = 0

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

(x + 1 ) (x + 510)

To summarize, since 1 and 510 multiply to 510 and add up 511, you know that the following is true:

x² + 511x + 510 = (x + 1 ) (x + 510)
