What two numbers multiply to -216 and add up to -69?

Here we answer the question: "What two numbers multiply to -216 and add up to -69?"

The answer to your question is:

-72 and 3

Below we illustrate and prove that -72 and 3 multiply to -216 and add up to -69:

-72 × 3 = -216
-72 + 3 = -69

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

x² - 69x - 216 = 0

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

(x - 72 ) (x + 3)

To summarize, since -72 and 3 multiply to -216 and add up -69, you know that the following is true:

x² - 69x - 216 = (x - 72 ) (x + 3)
