What two numbers multiply to -858 and add up to -17?

Here we answer the question: "What two numbers multiply to -858 and add up to -17?"

The answer to your question is:

-39 and 22

Below we illustrate and prove that -39 and 22 multiply to -858 and add up to -17:

-39 × 22 = -858
-39 + 22 = -17

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

x² - 17x - 858 = 0

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

(x - 39 ) (x + 22)

To summarize, since -39 and 22 multiply to -858 and add up -17, you know that the following is true:

x² - 17x - 858 = (x - 39 ) (x + 22)
