What two numbers multiply to -170 and add up to -83?

Here we answer the question: "What two numbers multiply to -170 and add up to -83?"

The answer to your question is:

-85 and 2

Below we illustrate and prove that -85 and 2 multiply to -170 and add up to -83:

-85 × 2 = -170
-85 + 2 = -83

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

x² - 83x - 170 = 0

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

(x - 85 ) (x + 2)

To summarize, since -85 and 2 multiply to -170 and add up -83, you know that the following is true:

x² - 83x - 170 = (x - 85 ) (x + 2)
