What two numbers multiply to 648 and add up to -219?

Here we answer the question: "What two numbers multiply to 648 and add up to -219?"

The answer to your question is:

-216 and -3

Below we illustrate and prove that -216 and -3 multiply to 648 and add up to -219:

-216 × -3 = 648
-216 + -3 = -219

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

x² - 219x + 648 = 0

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

(x - 216 ) (x - 3)

To summarize, since -216 and -3 multiply to 648 and add up -219, you know that the following is true:

x² - 219x + 648 = (x - 216 ) (x - 3)
