What two numbers multiply to -678 and add up to -223?

Here we answer the question: "What two numbers multiply to -678 and add up to -223?"

The answer to your question is:

-226 and 3

Below we illustrate and prove that -226 and 3 multiply to -678 and add up to -223:

-226 × 3 = -678
-226 + 3 = -223

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

x² - 223x - 678 = 0

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

(x - 226 ) (x + 3)

To summarize, since -226 and 3 multiply to -678 and add up -223, you know that the following is true:

x² - 223x - 678 = (x - 226 ) (x + 3)
