What two numbers multiply to -216 and add up to 106?

Here we answer the question: "What two numbers multiply to -216 and add up to 106?"

The answer to your question is:

-2 and 108

Below we illustrate and prove that -2 and 108 multiply to -216 and add up to 106:

-2 × 108 = -216
-2 + 108 = 106

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

x² + 106x - 216 = 0

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

(x - 2 ) (x + 108)

To summarize, since -2 and 108 multiply to -216 and add up 106, you know that the following is true:

x² + 106x - 216 = (x - 2 ) (x + 108)
