Here we answer the question: "What two numbers multiply to -440 and add up to -218?"

The answer to your question is:

-220 and 2


Below we illustrate and prove that -220 and 2 multiply to -440 and add up to -218:

-220 × 2 = -440
-220 + 2 = -218

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

x2 - 218x - 440 = 0

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

(x - 220 ) (x + 2)

To summarize, since -220 and 2 multiply to -440 and add up -218, you know that the following is true:

x2 - 218x - 440 = (x - 220 ) (x + 2)
