What two numbers multiply to 820 and add up to -412?

Here we answer the question: "What two numbers multiply to 820 and add up to -412?"

The answer to your question is:

-410 and -2

Below we illustrate and prove that -410 and -2 multiply to 820 and add up to -412:

-410 × -2 = 820
-410 + -2 = -412

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

x² - 412x + 820 = 0

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

(x - 410 ) (x - 2)

To summarize, since -410 and -2 multiply to 820 and add up -412, you know that the following is true:

x² - 412x + 820 = (x - 410 ) (x - 2)
