What two numbers multiply to 831 and add up to 280?

Here we answer the question: "What two numbers multiply to 831 and add up to 280?"

The answer to your question is:

3 and 277

Below we illustrate and prove that 3 and 277 multiply to 831 and add up to 280:

3 × 277 = 831
3 + 277 = 280

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

x² + 280x + 831 = 0

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

(x + 3 ) (x + 277)

To summarize, since 3 and 277 multiply to 831 and add up 280, you know that the following is true:

x² + 280x + 831 = (x + 3 ) (x + 277)
