What two numbers multiply to 168 and add up to -29?

Here we answer the question: "What two numbers multiply to 168 and add up to -29?"

The answer to your question is:

-21 and -8

Below we illustrate and prove that -21 and -8 multiply to 168 and add up to -29:

-21 × -8 = 168
-21 + -8 = -29

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

x² - 29x + 168 = 0

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

(x - 21 ) (x - 8)

To summarize, since -21 and -8 multiply to 168 and add up -29, you know that the following is true:

x² - 29x + 168 = (x - 21 ) (x - 8)
