What two numbers multiply to 422 and add up to -213?

Here we answer the question: "What two numbers multiply to 422 and add up to -213?"

The answer to your question is:

-211 and -2

Below we illustrate and prove that -211 and -2 multiply to 422 and add up to -213:

-211 × -2 = 422
-211 + -2 = -213

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

x² - 213x + 422 = 0

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

(x - 211 ) (x - 2)

To summarize, since -211 and -2 multiply to 422 and add up -213, you know that the following is true:

x² - 213x + 422 = (x - 211 ) (x - 2)
