What two numbers multiply to 621 and add up to -210?

Here we answer the question: "What two numbers multiply to 621 and add up to -210?"

The answer to your question is:

-207 and -3

Below we illustrate and prove that -207 and -3 multiply to 621 and add up to -210:

-207 × -3 = 621
-207 + -3 = -210

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

x² - 210x + 621 = 0

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

(x - 207 ) (x - 3)

To summarize, since -207 and -3 multiply to 621 and add up -210, you know that the following is true:

x² - 210x + 621 = (x - 207 ) (x - 3)
