What two numbers multiply to -164 and add up to -80?

Here we answer the question: "What two numbers multiply to -164 and add up to -80?"

The answer to your question is:

-82 and 2

Below we illustrate and prove that -82 and 2 multiply to -164 and add up to -80:

-82 × 2 = -164
-82 + 2 = -80

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

x² - 80x - 164 = 0

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

(x - 82 ) (x + 2)

To summarize, since -82 and 2 multiply to -164 and add up -80, you know that the following is true:

x² - 80x - 164 = (x - 82 ) (x + 2)
