What two numbers multiply to -864 and add up to 285?

Here we answer the question: "What two numbers multiply to -864 and add up to 285?"

The answer to your question is:

-3 and 288

Below we illustrate and prove that -3 and 288 multiply to -864 and add up to 285:

-3 × 288 = -864
-3 + 288 = 285

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

x² + 285x - 864 = 0

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

(x - 3 ) (x + 288)

To summarize, since -3 and 288 multiply to -864 and add up 285, you know that the following is true:

x² + 285x - 864 = (x - 3 ) (x + 288)
