What two numbers multiply to -440 and add up to 2?

Here we answer the question: "What two numbers multiply to -440 and add up to 2?"

The answer to your question is:

-20 and 22

Below we illustrate and prove that -20 and 22 multiply to -440 and add up to 2:

-20 × 22 = -440
-20 + 22 = 2

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

x² + 2x - 440 = 0

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

(x - 20 ) (x + 22)

To summarize, since -20 and 22 multiply to -440 and add up 2, you know that the following is true:

x² + 2x - 440 = (x - 20 ) (x + 22)
