What two numbers multiply to -543 and add up to 542?

Here we answer the question: "What two numbers multiply to -543 and add up to 542?"

The answer to your question is:

-1 and 543

Below we illustrate and prove that -1 and 543 multiply to -543 and add up to 542:

-1 × 543 = -543
-1 + 543 = 542

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

x² + 542x - 543 = 0

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

(x - 1 ) (x + 543)

To summarize, since -1 and 543 multiply to -543 and add up 542, you know that the following is true:

x² + 542x - 543 = (x - 1 ) (x + 543)
