What two numbers multiply to -822 and add up to -409?

Here we answer the question: "What two numbers multiply to -822 and add up to -409?"

The answer to your question is:

-411 and 2

Below we illustrate and prove that -411 and 2 multiply to -822 and add up to -409:

-411 × 2 = -822
-411 + 2 = -409

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

x² - 409x - 822 = 0

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

(x - 411 ) (x + 2)

To summarize, since -411 and 2 multiply to -822 and add up -409, you know that the following is true:

x² - 409x - 822 = (x - 411 ) (x + 2)
