What two numbers multiply to 395 and add up to -84?

Here we answer the question: "What two numbers multiply to 395 and add up to -84?"

The answer to your question is:

-79 and -5

Below we illustrate and prove that -79 and -5 multiply to 395 and add up to -84:

-79 × -5 = 395
-79 + -5 = -84

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

x² - 84x + 395 = 0

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

(x - 79 ) (x - 5)

To summarize, since -79 and -5 multiply to 395 and add up -84, you know that the following is true:

x² - 84x + 395 = (x - 79 ) (x - 5)
