What two numbers multiply to 397 and add up to 398?

Here we answer the question: "What two numbers multiply to 397 and add up to 398?"

The answer to your question is:

1 and 397

Below we illustrate and prove that 1 and 397 multiply to 397 and add up to 398:

1 × 397 = 397
1 + 397 = 398

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

x² + 398x + 397 = 0

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

(x + 1 ) (x + 397)

To summarize, since 1 and 397 multiply to 397 and add up 398, you know that the following is true:

x² + 398x + 397 = (x + 1 ) (x + 397)
