What two numbers multiply to 630 and add up to 213?

Here we answer the question: "What two numbers multiply to 630 and add up to 213?"

The answer to your question is:

3 and 210

Below we illustrate and prove that 3 and 210 multiply to 630 and add up to 213:

3 × 210 = 630
3 + 210 = 213

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

x² + 213x + 630 = 0

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

(x + 3 ) (x + 210)

To summarize, since 3 and 210 multiply to 630 and add up 213, you know that the following is true:

x² + 213x + 630 = (x + 3 ) (x + 210)
