What two numbers multiply to -856 and add up to -210?

Here we answer the question: "What two numbers multiply to -856 and add up to -210?"

The answer to your question is:

-214 and 4

Below we illustrate and prove that -214 and 4 multiply to -856 and add up to -210:

-214 × 4 = -856
-214 + 4 = -210

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

x² - 210x - 856 = 0

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

(x - 214 ) (x + 4)

To summarize, since -214 and 4 multiply to -856 and add up -210, you know that the following is true:

x² - 210x - 856 = (x - 214 ) (x + 4)
