What two numbers multiply to -436 and add up to 216?

Here we answer the question: "What two numbers multiply to -436 and add up to 216?"

The answer to your question is:

-2 and 218

Below we illustrate and prove that -2 and 218 multiply to -436 and add up to 216:

-2 × 218 = -436
-2 + 218 = 216

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

x² + 216x - 436 = 0

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

(x - 2 ) (x + 218)

To summarize, since -2 and 218 multiply to -436 and add up 216, you know that the following is true:

x² + 216x - 436 = (x - 2 ) (x + 218)
