What two numbers multiply to -693 and add up to 228?

Here we answer the question: "What two numbers multiply to -693 and add up to 228?"

The answer to your question is:

-3 and 231

Below we illustrate and prove that -3 and 231 multiply to -693 and add up to 228:

-3 × 231 = -693
-3 + 231 = 228

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

x² + 228x - 693 = 0

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

(x - 3 ) (x + 231)

To summarize, since -3 and 231 multiply to -693 and add up 228, you know that the following is true:

x² + 228x - 693 = (x - 3 ) (x + 231)
