What two numbers multiply to -510 and add up to -509?

Here we answer the question: "What two numbers multiply to -510 and add up to -509?"

The answer to your question is:

-510 and 1

Below we illustrate and prove that -510 and 1 multiply to -510 and add up to -509:

-510 × 1 = -510
-510 + 1 = -509

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

x² - 509x - 510 = 0

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

(x - 510 ) (x + 1)

To summarize, since -510 and 1 multiply to -510 and add up -509, you know that the following is true:

x² - 509x - 510 = (x - 510 ) (x + 1)
