What two numbers multiply to 216 and add up to -30?

Here we answer the question: "What two numbers multiply to 216 and add up to -30?"

The answer to your question is:

-18 and -12

Below we illustrate and prove that -18 and -12 multiply to 216 and add up to -30:

-18 × -12 = 216
-18 + -12 = -30

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

x² - 30x + 216 = 0

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

(x - 18 ) (x - 12)

To summarize, since -18 and -12 multiply to 216 and add up -30, you know that the following is true:

x² - 30x + 216 = (x - 18 ) (x - 12)
