What two numbers multiply to -228 and add up to 227?

Here we answer the question: "What two numbers multiply to -228 and add up to 227?"

The answer to your question is:

-1 and 228

Below we illustrate and prove that -1 and 228 multiply to -228 and add up to 227:

-1 × 228 = -228
-1 + 228 = 227

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

x² + 227x - 228 = 0

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

(x - 1 ) (x + 228)

To summarize, since -1 and 228 multiply to -228 and add up 227, you know that the following is true:

x² + 227x - 228 = (x - 1 ) (x + 228)
