What two numbers multiply to -251 and add up to 250?

Here we answer the question: "What two numbers multiply to -251 and add up to 250?"

The answer to your question is:

-1 and 251

Below we illustrate and prove that -1 and 251 multiply to -251 and add up to 250:

-1 × 251 = -251
-1 + 251 = 250

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

x² + 250x - 251 = 0

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

(x - 1 ) (x + 251)

To summarize, since -1 and 251 multiply to -251 and add up 250, you know that the following is true:

x² + 250x - 251 = (x - 1 ) (x + 251)
