What two numbers multiply to -229 and add up to 228?

Here we answer the question: "What two numbers multiply to -229 and add up to 228?"

The answer to your question is:

-1 and 229

Below we illustrate and prove that -1 and 229 multiply to -229 and add up to 228:

-1 × 229 = -229
-1 + 229 = 228

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

x² + 228x - 229 = 0

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

(x - 1 ) (x + 229)

To summarize, since -1 and 229 multiply to -229 and add up 228, you know that the following is true:

x² + 228x - 229 = (x - 1 ) (x + 229)
