What two numbers multiply to -860 and add up to 211?

Here we answer the question: "What two numbers multiply to -860 and add up to 211?"

The answer to your question is:

-4 and 215

Below we illustrate and prove that -4 and 215 multiply to -860 and add up to 211:

-4 × 215 = -860
-4 + 215 = 211

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

x² + 211x - 860 = 0

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

(x - 4 ) (x + 215)

To summarize, since -4 and 215 multiply to -860 and add up 211, you know that the following is true:

x² + 211x - 860 = (x - 4 ) (x + 215)
