What two numbers multiply to 840 and add up to -173?

Here we answer the question: "What two numbers multiply to 840 and add up to -173?"

The answer to your question is:

-168 and -5

Below we illustrate and prove that -168 and -5 multiply to 840 and add up to -173:

-168 × -5 = 840
-168 + -5 = -173

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

x² - 173x + 840 = 0

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

(x - 168 ) (x - 5)

To summarize, since -168 and -5 multiply to 840 and add up -173, you know that the following is true:

x² - 173x + 840 = (x - 168 ) (x - 5)
