What two numbers multiply to 438 and add up to 439?

Here we answer the question: "What two numbers multiply to 438 and add up to 439?"

The answer to your question is:

1 and 438

Below we illustrate and prove that 1 and 438 multiply to 438 and add up to 439:

1 × 438 = 438
1 + 438 = 439

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

x² + 439x + 438 = 0

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

(x + 1 ) (x + 438)

To summarize, since 1 and 438 multiply to 438 and add up 439, you know that the following is true:

x² + 439x + 438 = (x + 1 ) (x + 438)
