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:

-4 and 171

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

-4 × 171 = -684
-4 + 171 = 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 - 4 ) (x + 171)

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

x² + 167x - 684 = (x - 4 ) (x + 171)
