What two numbers multiply to -558 and add up to -13?

Here we answer the question: "What two numbers multiply to -558 and add up to -13?"

The answer to your question is:

-31 and 18

Below we illustrate and prove that -31 and 18 multiply to -558 and add up to -13:

-31 × 18 = -558
-31 + 18 = -13

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

x² - 13x - 558 = 0

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

(x - 31 ) (x + 18)

To summarize, since -31 and 18 multiply to -558 and add up -13, you know that the following is true:

x² - 13x - 558 = (x - 31 ) (x + 18)
