What two numbers multiply to -255 and add up to -82?

Here we answer the question: "What two numbers multiply to -255 and add up to -82?"

The answer to your question is:

-85 and 3

Below we illustrate and prove that -85 and 3 multiply to -255 and add up to -82:

-85 × 3 = -255
-85 + 3 = -82

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

x² - 82x - 255 = 0

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

(x - 85 ) (x + 3)

To summarize, since -85 and 3 multiply to -255 and add up -82, you know that the following is true:

x² - 82x - 255 = (x - 85 ) (x + 3)
