What two numbers multiply to -984 and add up to 115?

Here we answer the question: "What two numbers multiply to -984 and add up to 115?"

The answer to your question is:

-8 and 123

Below we illustrate and prove that -8 and 123 multiply to -984 and add up to 115:

-8 × 123 = -984
-8 + 123 = 115

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

x² + 115x - 984 = 0

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

(x - 8 ) (x + 123)

To summarize, since -8 and 123 multiply to -984 and add up 115, you know that the following is true:

x² + 115x - 984 = (x - 8 ) (x + 123)
