What two numbers multiply to -117 and add up to 4?

Here we answer the question: "What two numbers multiply to -117 and add up to 4?"

The answer to your question is:

-9 and 13

Below we illustrate and prove that -9 and 13 multiply to -117 and add up to 4:

-9 × 13 = -117
-9 + 13 = 4

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

x² + 4x - 117 = 0

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

(x - 9 ) (x + 13)

To summarize, since -9 and 13 multiply to -117 and add up 4, you know that the following is true:

x² + 4x - 117 = (x - 9 ) (x + 13)
