What two numbers multiply to 168 and add up to -86?

Here we answer the question: "What two numbers multiply to 168 and add up to -86?"

The answer to your question is:

-84 and -2

Below we illustrate and prove that -84 and -2 multiply to 168 and add up to -86:

-84 × -2 = 168
-84 + -2 = -86

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

x² - 86x + 168 = 0

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

(x - 84 ) (x - 2)

To summarize, since -84 and -2 multiply to 168 and add up -86, you know that the following is true:

x² - 86x + 168 = (x - 84 ) (x - 2)
