What two numbers multiply to 921 and add up to 310?

Here we answer the question: "What two numbers multiply to 921 and add up to 310?"

The answer to your question is:

3 and 307

Below we illustrate and prove that 3 and 307 multiply to 921 and add up to 310:

3 × 307 = 921
3 + 307 = 310

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

x² + 310x + 921 = 0

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

(x + 3 ) (x + 307)

To summarize, since 3 and 307 multiply to 921 and add up 310, you know that the following is true:

x² + 310x + 921 = (x + 3 ) (x + 307)
