What two numbers multiply to -684 and add up to 225?

Here we answer the question: "What two numbers multiply to -684 and add up to 225?"

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 225:

-3 × 228 = -684
-3 + 228 = 225

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

x² + 225x - 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 225, you know that the following is true:

x² + 225x - 684 = (x - 3 ) (x + 228)
