What two numbers multiply to -431 and add up to 430?

Here we answer the question: "What two numbers multiply to -431 and add up to 430?"

The answer to your question is:

-1 and 431

Below we illustrate and prove that -1 and 431 multiply to -431 and add up to 430:

-1 × 431 = -431
-1 + 431 = 430

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

x² + 430x - 431 = 0

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

(x - 1 ) (x + 431)

To summarize, since -1 and 431 multiply to -431 and add up 430, you know that the following is true:

x² + 430x - 431 = (x - 1 ) (x + 431)
