What two numbers multiply to -540 and add up to 539?

Here we answer the question: "What two numbers multiply to -540 and add up to 539?"

The answer to your question is:

-1 and 540

Below we illustrate and prove that -1 and 540 multiply to -540 and add up to 539:

-1 × 540 = -540
-1 + 540 = 539

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

x² + 539x - 540 = 0

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

(x - 1 ) (x + 540)

To summarize, since -1 and 540 multiply to -540 and add up 539, you know that the following is true:

x² + 539x - 540 = (x - 1 ) (x + 540)
