What two numbers multiply to 417 and add up to -418?

Here we answer the question: "What two numbers multiply to 417 and add up to -418?"

The answer to your question is:

-417 and -1

Below we illustrate and prove that -417 and -1 multiply to 417 and add up to -418:

-417 × -1 = 417
-417 + -1 = -418

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

x² - 418x + 417 = 0

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

(x - 417 ) (x - 1)

To summarize, since -417 and -1 multiply to 417 and add up -418, you know that the following is true:

x² - 418x + 417 = (x - 417 ) (x - 1)
