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:

3 and 207

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

3 × 207 = 621
3 + 207 = 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 + 3 ) (x + 207)

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

x² + 210x + 621 = (x + 3 ) (x + 207)
