What two numbers multiply to 248 and add up to -39?

Here we answer the question: "What two numbers multiply to 248 and add up to -39?"

The answer to your question is:

-31 and -8

Below we illustrate and prove that -31 and -8 multiply to 248 and add up to -39:

-31 × -8 = 248
-31 + -8 = -39

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

x² - 39x + 248 = 0

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

(x - 31 ) (x - 8)

To summarize, since -31 and -8 multiply to 248 and add up -39, you know that the following is true:

x² - 39x + 248 = (x - 31 ) (x - 8)
