What two numbers multiply to -455 and add up to 454?

Here we answer the question: "What two numbers multiply to -455 and add up to 454?"

The answer to your question is:

-1 and 455

Below we illustrate and prove that -1 and 455 multiply to -455 and add up to 454:

-1 × 455 = -455
-1 + 455 = 454

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

x² + 454x - 455 = 0

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

(x - 1 ) (x + 455)

To summarize, since -1 and 455 multiply to -455 and add up 454, you know that the following is true:

x² + 454x - 455 = (x - 1 ) (x + 455)
