What two numbers multiply to -220 and add up to -219?

Here we answer the question: "What two numbers multiply to -220 and add up to -219?"

The answer to your question is:

-220 and 1

Below we illustrate and prove that -220 and 1 multiply to -220 and add up to -219:

-220 × 1 = -220
-220 + 1 = -219

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

x² - 219x - 220 = 0

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

(x - 220 ) (x + 1)

To summarize, since -220 and 1 multiply to -220 and add up -219, you know that the following is true:

x² - 219x - 220 = (x - 220 ) (x + 1)
