What two numbers multiply to 798 and add up to -401?

Here we answer the question: "What two numbers multiply to 798 and add up to -401?"

The answer to your question is:

-399 and -2

Below we illustrate and prove that -399 and -2 multiply to 798 and add up to -401:

-399 × -2 = 798
-399 + -2 = -401

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

x² - 401x + 798 = 0

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

(x - 399 ) (x - 2)

To summarize, since -399 and -2 multiply to 798 and add up -401, you know that the following is true:

x² - 401x + 798 = (x - 399 ) (x - 2)
