What two numbers multiply to 319 and add up to 320?

Here we answer the question: "What two numbers multiply to 319 and add up to 320?"

The answer to your question is:

1 and 319

Below we illustrate and prove that 1 and 319 multiply to 319 and add up to 320:

1 × 319 = 319
1 + 319 = 320

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

x² + 320x + 319 = 0

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

(x + 1 ) (x + 319)

To summarize, since 1 and 319 multiply to 319 and add up 320, you know that the following is true:

x² + 320x + 319 = (x + 1 ) (x + 319)
