What two numbers multiply to -168 and add up to -38?

Here we answer the question: "What two numbers multiply to -168 and add up to -38?"

The answer to your question is:

-42 and 4

Below we illustrate and prove that -42 and 4 multiply to -168 and add up to -38:

-42 × 4 = -168
-42 + 4 = -38

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

x² - 38x - 168 = 0

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

(x - 42 ) (x + 4)

To summarize, since -42 and 4 multiply to -168 and add up -38, you know that the following is true:

x² - 38x - 168 = (x - 42 ) (x + 4)
