What two numbers multiply to -539 and add up to 538?

Here we answer the question: "What two numbers multiply to -539 and add up to 538?"

The answer to your question is:

-1 and 539

Below we illustrate and prove that -1 and 539 multiply to -539 and add up to 538:

-1 × 539 = -539
-1 + 539 = 538

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

x² + 538x - 539 = 0

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

(x - 1 ) (x + 539)

To summarize, since -1 and 539 multiply to -539 and add up 538, you know that the following is true:

x² + 538x - 539 = (x - 1 ) (x + 539)
