What two numbers multiply to 396 and add up to 397?

Here we answer the question: "What two numbers multiply to 396 and add up to 397?"

The answer to your question is:

1 and 396

Below we illustrate and prove that 1 and 396 multiply to 396 and add up to 397:

1 × 396 = 396
1 + 396 = 397

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

x² + 397x + 396 = 0

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

(x + 1 ) (x + 396)

To summarize, since 1 and 396 multiply to 396 and add up 397, you know that the following is true:

x² + 397x + 396 = (x + 1 ) (x + 396)
