What two numbers multiply to -684 and add up to 67?

Here we answer the question: "What two numbers multiply to -684 and add up to 67?"

The answer to your question is:

-9 and 76

Below we illustrate and prove that -9 and 76 multiply to -684 and add up to 67:

-9 × 76 = -684
-9 + 76 = 67

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

x² + 67x - 684 = 0

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

(x - 9 ) (x + 76)

To summarize, since -9 and 76 multiply to -684 and add up 67, you know that the following is true:

x² + 67x - 684 = (x - 9 ) (x + 76)
