What two numbers multiply to 864 and add up to -220?

Here we answer the question: "What two numbers multiply to 864 and add up to -220?"

The answer to your question is:

-216 and -4

Below we illustrate and prove that -216 and -4 multiply to 864 and add up to -220:

-216 × -4 = 864
-216 + -4 = -220

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

x² - 220x + 864 = 0

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

(x - 216 ) (x - 4)

To summarize, since -216 and -4 multiply to 864 and add up -220, you know that the following is true:

x² - 220x + 864 = (x - 216 ) (x - 4)
