What two numbers multiply to 210 and add up to -211?

Here we answer the question: "What two numbers multiply to 210 and add up to -211?"

The answer to your question is:

-210 and -1

Below we illustrate and prove that -210 and -1 multiply to 210 and add up to -211:

-210 × -1 = 210
-210 + -1 = -211

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

x² - 211x + 210 = 0

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

(x - 210 ) (x - 1)

To summarize, since -210 and -1 multiply to 210 and add up -211, you know that the following is true:

x² - 211x + 210 = (x - 210 ) (x - 1)
