What two numbers multiply to -558 and add up to 557?

Here we answer the question: "What two numbers multiply to -558 and add up to 557?"

The answer to your question is:

-1 and 558

Below we illustrate and prove that -1 and 558 multiply to -558 and add up to 557:

-1 × 558 = -558
-1 + 558 = 557

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

x² + 557x - 558 = 0

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

(x - 1 ) (x + 558)

To summarize, since -1 and 558 multiply to -558 and add up 557, you know that the following is true:

x² + 557x - 558 = (x - 1 ) (x + 558)
