What two numbers multiply to -216 and add up to 50?

Here we answer the question: "What two numbers multiply to -216 and add up to 50?"

The answer to your question is:

-4 and 54

Below we illustrate and prove that -4 and 54 multiply to -216 and add up to 50:

-4 × 54 = -216
-4 + 54 = 50

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

x² + 50x - 216 = 0

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

(x - 4 ) (x + 54)

To summarize, since -4 and 54 multiply to -216 and add up 50, you know that the following is true:

x² + 50x - 216 = (x - 4 ) (x + 54)
