What two numbers multiply to -856 and add up to 99?

Here we answer the question: "What two numbers multiply to -856 and add up to 99?"

The answer to your question is:

-8 and 107

Below we illustrate and prove that -8 and 107 multiply to -856 and add up to 99:

-8 × 107 = -856
-8 + 107 = 99

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

x² + 99x - 856 = 0

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

(x - 8 ) (x + 107)

To summarize, since -8 and 107 multiply to -856 and add up 99, you know that the following is true:

x² + 99x - 856 = (x - 8 ) (x + 107)
