What two numbers multiply to 85 and add up to -22?

Here we answer the question: "What two numbers multiply to 85 and add up to -22?"

The answer to your question is:

-17 and -5

Below we illustrate and prove that -17 and -5 multiply to 85 and add up to -22:

-17 × -5 = 85
-17 + -5 = -22

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

x² - 22x + 85 = 0

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

(x - 17 ) (x - 5)

To summarize, since -17 and -5 multiply to 85 and add up -22, you know that the following is true:

x² - 22x + 85 = (x - 17 ) (x - 5)
