What two numbers multiply to -248 and add up to 247?

Here we answer the question: "What two numbers multiply to -248 and add up to 247?"

The answer to your question is:

-1 and 248

Below we illustrate and prove that -1 and 248 multiply to -248 and add up to 247:

-1 × 248 = -248
-1 + 248 = 247

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

x² + 247x - 248 = 0

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

(x - 1 ) (x + 248)

To summarize, since -1 and 248 multiply to -248 and add up 247, you know that the following is true:

x² + 247x - 248 = (x - 1 ) (x + 248)
