What two numbers multiply to -248 and add up to 23?

Here we answer the question: "What two numbers multiply to -248 and add up to 23?"

The answer to your question is:

-8 and 31

Below we illustrate and prove that -8 and 31 multiply to -248 and add up to 23:

-8 × 31 = -248
-8 + 31 = 23

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

x² + 23x - 248 = 0

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

(x - 8 ) (x + 31)

To summarize, since -8 and 31 multiply to -248 and add up 23, you know that the following is true:

x² + 23x - 248 = (x - 8 ) (x + 31)
