What two numbers multiply to -515 and add up to 514?

Here we answer the question: "What two numbers multiply to -515 and add up to 514?"

The answer to your question is:

-1 and 515

Below we illustrate and prove that -1 and 515 multiply to -515 and add up to 514:

-1 × 515 = -515
-1 + 515 = 514

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

x² + 514x - 515 = 0

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

(x - 1 ) (x + 515)

To summarize, since -1 and 515 multiply to -515 and add up 514, you know that the following is true:

x² + 514x - 515 = (x - 1 ) (x + 515)
