What two numbers multiply to -438 and add up to 217?

Here we answer the question: "What two numbers multiply to -438 and add up to 217?"

The answer to your question is:

-2 and 219

Below we illustrate and prove that -2 and 219 multiply to -438 and add up to 217:

-2 × 219 = -438
-2 + 219 = 217

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

x² + 217x - 438 = 0

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

(x - 2 ) (x + 219)

To summarize, since -2 and 219 multiply to -438 and add up 217, you know that the following is true:

x² + 217x - 438 = (x - 2 ) (x + 219)
