What two numbers multiply to 684 and add up to -231?

Here we answer the question: "What two numbers multiply to 684 and add up to -231?"

The answer to your question is:

-228 and -3

Below we illustrate and prove that -228 and -3 multiply to 684 and add up to -231:

-228 × -3 = 684
-228 + -3 = -231

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

x² - 231x + 684 = 0

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

(x - 228 ) (x - 3)

To summarize, since -228 and -3 multiply to 684 and add up -231, you know that the following is true:

x² - 231x + 684 = (x - 228 ) (x - 3)
