What two numbers multiply to -441 and add up to 440?

Here we answer the question: "What two numbers multiply to -441 and add up to 440?"

The answer to your question is:

-1 and 441

Below we illustrate and prove that -1 and 441 multiply to -441 and add up to 440:

-1 × 441 = -441
-1 + 441 = 440

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

x² + 440x - 441 = 0

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

(x - 1 ) (x + 441)

To summarize, since -1 and 441 multiply to -441 and add up 440, you know that the following is true:

x² + 440x - 441 = (x - 1 ) (x + 441)
