What two numbers multiply to 415 and add up to 416?

Here we answer the question: "What two numbers multiply to 415 and add up to 416?"

The answer to your question is:

1 and 415

Below we illustrate and prove that 1 and 415 multiply to 415 and add up to 416:

1 × 415 = 415
1 + 415 = 416

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

x² + 416x + 415 = 0

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

(x + 1 ) (x + 415)

To summarize, since 1 and 415 multiply to 415 and add up 416, you know that the following is true:

x² + 416x + 415 = (x + 1 ) (x + 415)
