What two numbers multiply to 416 and add up to -210?

Here we answer the question: "What two numbers multiply to 416 and add up to -210?"

The answer to your question is:

-208 and -2

Below we illustrate and prove that -208 and -2 multiply to 416 and add up to -210:

-208 × -2 = 416
-208 + -2 = -210

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

x² - 210x + 416 = 0

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

(x - 208 ) (x - 2)

To summarize, since -208 and -2 multiply to 416 and add up -210, you know that the following is true:

x² - 210x + 416 = (x - 208 ) (x - 2)
