What two numbers multiply to -678 and add up to -107?

Here we answer the question: "What two numbers multiply to -678 and add up to -107?"

The answer to your question is:

-113 and 6

Below we illustrate and prove that -113 and 6 multiply to -678 and add up to -107:

-113 × 6 = -678
-113 + 6 = -107

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

x² - 107x - 678 = 0

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

(x - 113 ) (x + 6)

To summarize, since -113 and 6 multiply to -678 and add up -107, you know that the following is true:

x² - 107x - 678 = (x - 113 ) (x + 6)
