What two numbers multiply to -558 and add up to 277?

Here we answer the question: "What two numbers multiply to -558 and add up to 277?"

The answer to your question is:

-2 and 279

Below we illustrate and prove that -2 and 279 multiply to -558 and add up to 277:

-2 × 279 = -558
-2 + 279 = 277

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

x² + 277x - 558 = 0

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

(x - 2 ) (x + 279)

To summarize, since -2 and 279 multiply to -558 and add up 277, you know that the following is true:

x² + 277x - 558 = (x - 2 ) (x + 279)
