What two numbers multiply to 864 and add up to -291?

Here we answer the question: "What two numbers multiply to 864 and add up to -291?"

The answer to your question is:

-288 and -3

Below we illustrate and prove that -288 and -3 multiply to 864 and add up to -291:

-288 × -3 = 864
-288 + -3 = -291

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

x² - 291x + 864 = 0

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

(x - 288 ) (x - 3)

To summarize, since -288 and -3 multiply to 864 and add up -291, you know that the following is true:

x² - 291x + 864 = (x - 288 ) (x - 3)
