What two numbers multiply to 410 and add up to -411?

Here we answer the question: "What two numbers multiply to 410 and add up to -411?"

The answer to your question is:

-410 and -1

Below we illustrate and prove that -410 and -1 multiply to 410 and add up to -411:

-410 × -1 = 410
-410 + -1 = -411

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

x² - 411x + 410 = 0

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

(x - 410 ) (x - 1)

To summarize, since -410 and -1 multiply to 410 and add up -411, you know that the following is true:

x² - 411x + 410 = (x - 410 ) (x - 1)
