What two numbers multiply to 385 and add up to -82?

Here we answer the question: "What two numbers multiply to 385 and add up to -82?"

The answer to your question is:

-77 and -5

Below we illustrate and prove that -77 and -5 multiply to 385 and add up to -82:

-77 × -5 = 385
-77 + -5 = -82

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

x² - 82x + 385 = 0

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

(x - 77 ) (x - 5)

To summarize, since -77 and -5 multiply to 385 and add up -82, you know that the following is true:

x² - 82x + 385 = (x - 77 ) (x - 5)
