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

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

The answer to your question is:

-440 and -1

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

-440 × -1 = 440
-440 + -1 = -441

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

x² - 441x + 440 = 0

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

(x - 440 ) (x - 1)

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

x² - 441x + 440 = (x - 440 ) (x - 1)
