What two numbers multiply to 678 and add up to -229?

Here we answer the question: "What two numbers multiply to 678 and add up to -229?"

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 -229:

-226 × -3 = 678
-226 + -3 = -229

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

x² - 229x + 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 -229, you know that the following is true:

x² - 229x + 678 = (x - 226 ) (x - 3)
