What two numbers multiply to -861 and add up to 116?

Here we answer the question: "What two numbers multiply to -861 and add up to 116?"

The answer to your question is:

-7 and 123

Below we illustrate and prove that -7 and 123 multiply to -861 and add up to 116:

-7 × 123 = -861
-7 + 123 = 116

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

x² + 116x - 861 = 0

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

(x - 7 ) (x + 123)

To summarize, since -7 and 123 multiply to -861 and add up 116, you know that the following is true:

x² + 116x - 861 = (x - 7 ) (x + 123)
