What two numbers multiply to -888 and add up to 218?

Here we answer the question: "What two numbers multiply to -888 and add up to 218?"

The answer to your question is:

-4 and 222

Below we illustrate and prove that -4 and 222 multiply to -888 and add up to 218:

-4 × 222 = -888
-4 + 222 = 218

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

x² + 218x - 888 = 0

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

(x - 4 ) (x + 222)

To summarize, since -4 and 222 multiply to -888 and add up 218, you know that the following is true:

x² + 218x - 888 = (x - 4 ) (x + 222)
