Here we answer the question: "What two numbers multiply to 416 and add up to -417?"

The answer to your question is:

-416 and -1

Below we illustrate and prove that -416 and -1 multiply to 416 and add up to -417:

-416 × -1 = 416
-416 + -1 = -417

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

x² - 417x + 416 = 0

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

(x - 416 ) (x - 1)

To summarize, since -416 and -1 multiply to 416 and add up -417, you know that the following is true:

x² - 417x + 416 = (x - 416 ) (x - 1)
