What two numbers multiply to -621 and add up to 204?

Here we answer the question: "What two numbers multiply to -621 and add up to 204?"

The answer to your question is:

-3 and 207

Below we illustrate and prove that -3 and 207 multiply to -621 and add up to 204:

-3 × 207 = -621
-3 + 207 = 204

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

x² + 204x - 621 = 0

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

(x - 3 ) (x + 207)

To summarize, since -3 and 207 multiply to -621 and add up 204, you know that the following is true:

x² + 204x - 621 = (x - 3 ) (x + 207)
