What two numbers multiply to 636 and add up to -320?

Here we answer the question: "What two numbers multiply to 636 and add up to -320?"

The answer to your question is:

-318 and -2

Below we illustrate and prove that -318 and -2 multiply to 636 and add up to -320:

-318 × -2 = 636
-318 + -2 = -320

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

x² - 320x + 636 = 0

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

(x - 318 ) (x - 2)

To summarize, since -318 and -2 multiply to 636 and add up -320, you know that the following is true:

x² - 320x + 636 = (x - 318 ) (x - 2)
