What two numbers multiply to 439 and add up to 440?

Here we answer the question: "What two numbers multiply to 439 and add up to 440?"

The answer to your question is:

1 and 439

Below we illustrate and prove that 1 and 439 multiply to 439 and add up to 440:

1 × 439 = 439
1 + 439 = 440

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

x² + 440x + 439 = 0

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

(x + 1 ) (x + 439)

To summarize, since 1 and 439 multiply to 439 and add up 440, you know that the following is true:

x² + 440x + 439 = (x + 1 ) (x + 439)
