What two numbers multiply to 836 and add up to -213?

Here we answer the question: "What two numbers multiply to 836 and add up to -213?"

The answer to your question is:

-209 and -4

Below we illustrate and prove that -209 and -4 multiply to 836 and add up to -213:

-209 × -4 = 836
-209 + -4 = -213

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

x² - 213x + 836 = 0

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

(x - 209 ) (x - 4)

To summarize, since -209 and -4 multiply to 836 and add up -213, you know that the following is true:

x² - 213x + 836 = (x - 209 ) (x - 4)
