What two numbers multiply to -684 and add up to -167?

Here we answer the question: "What two numbers multiply to -684 and add up to -167?"

The answer to your question is:

-171 and 4

Below we illustrate and prove that -171 and 4 multiply to -684 and add up to -167:

-171 × 4 = -684
-171 + 4 = -167

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

x² - 167x - 684 = 0

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

(x - 171 ) (x + 4)

To summarize, since -171 and 4 multiply to -684 and add up -167, you know that the following is true:

x² - 167x - 684 = (x - 171 ) (x + 4)
