What two numbers multiply to 85 and add up to -86?

Here we answer the question: "What two numbers multiply to 85 and add up to -86?"

The answer to your question is:

-85 and -1

Below we illustrate and prove that -85 and -1 multiply to 85 and add up to -86:

-85 × -1 = 85
-85 + -1 = -86

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

x² - 86x + 85 = 0

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

(x - 85 ) (x - 1)

To summarize, since -85 and -1 multiply to 85 and add up -86, you know that the following is true:

x² - 86x + 85 = (x - 85 ) (x - 1)
