What two numbers multiply to -876 and add up to 215?

Here we answer the question: "What two numbers multiply to -876 and add up to 215?"

The answer to your question is:

-4 and 219

Below we illustrate and prove that -4 and 219 multiply to -876 and add up to 215:

-4 × 219 = -876
-4 + 219 = 215

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

x² + 215x - 876 = 0

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

(x - 4 ) (x + 219)

To summarize, since -4 and 219 multiply to -876 and add up 215, you know that the following is true:

x² + 215x - 876 = (x - 4 ) (x + 219)
