What two numbers multiply to 864 and add up to -105?

Here we answer the question: "What two numbers multiply to 864 and add up to -105?"

The answer to your question is:

-96 and -9

Below we illustrate and prove that -96 and -9 multiply to 864 and add up to -105:

-96 × -9 = 864
-96 + -9 = -105

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

x² - 105x + 864 = 0

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

(x - 96 ) (x - 9)

To summarize, since -96 and -9 multiply to 864 and add up -105, you know that the following is true:

x² - 105x + 864 = (x - 96 ) (x - 9)
