What two numbers multiply to 836 and add up to -420?

Here we answer the question: "What two numbers multiply to 836 and add up to -420?"

The answer to your question is:

-418 and -2

Below we illustrate and prove that -418 and -2 multiply to 836 and add up to -420:

-418 × -2 = 836
-418 + -2 = -420

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

x² - 420x + 836 = 0

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

(x - 418 ) (x - 2)

To summarize, since -418 and -2 multiply to 836 and add up -420, you know that the following is true:

x² - 420x + 836 = (x - 418 ) (x - 2)
