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:

3 and 228

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

3 × 228 = 684
3 + 228 = 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 + 3 ) (x + 228)

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

x² + 231x + 684 = (x + 3 ) (x + 228)
