What two numbers multiply to 164 and add up to -84?

Here we answer the question: "What two numbers multiply to 164 and add up to -84?"

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 -84:

-82 × -2 = 164
-82 + -2 = -84

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

x² - 84x + 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 -84, you know that the following is true:

x² - 84x + 164 = (x - 82 ) (x - 2)
