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:

-36 and 6

Below we illustrate and prove that -36 and 6 multiply to -216 and add up to -30:

-36 × 6 = -216
-36 + 6 = -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 - 36 ) (x + 6)

To summarize, since -36 and 6 multiply to -216 and add up -30, you know that the following is true:

x² - 30x - 216 = (x - 36 ) (x + 6)
