What two numbers multiply to -669 and add up to -220?

Here we answer the question: "What two numbers multiply to -669 and add up to -220?"

The answer to your question is:

-223 and 3

Below we illustrate and prove that -223 and 3 multiply to -669 and add up to -220:

-223 × 3 = -669
-223 + 3 = -220

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

x² - 220x - 669 = 0

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

(x - 223 ) (x + 3)

To summarize, since -223 and 3 multiply to -669 and add up -220, you know that the following is true:

x² - 220x - 669 = (x - 223 ) (x + 3)
