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:

-210 and -3

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

-210 × -3 = 630
-210 + -3 = -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 - 210 ) (x - 3)

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

x² - 213x + 630 = (x - 210 ) (x - 3)
