What two numbers multiply to -249 and add up to 248?

Here we answer the question: "What two numbers multiply to -249 and add up to 248?"

The answer to your question is:

-1 and 249

Below we illustrate and prove that -1 and 249 multiply to -249 and add up to 248:

-1 × 249 = -249
-1 + 249 = 248

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

x² + 248x - 249 = 0

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

(x - 1 ) (x + 249)

To summarize, since -1 and 249 multiply to -249 and add up 248, you know that the following is true:

x² + 248x - 249 = (x - 1 ) (x + 249)
