What two numbers multiply to 168 and add up to -169?

Here we answer the question: "What two numbers multiply to 168 and add up to -169?"

The answer to your question is:

-168 and -1

Below we illustrate and prove that -168 and -1 multiply to 168 and add up to -169:

-168 × -1 = 168
-168 + -1 = -169

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

x² - 169x + 168 = 0

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

(x - 168 ) (x - 1)

To summarize, since -168 and -1 multiply to 168 and add up -169, you know that the following is true:

x² - 169x + 168 = (x - 168 ) (x - 1)
