What two numbers multiply to 216 and add up to -42?

Here we answer the question: "What two numbers multiply to 216 and add up to -42?"

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 -42:

-36 × -6 = 216
-36 + -6 = -42

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

x² - 42x + 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 -42, you know that the following is true:

x² - 42x + 216 = (x - 36 ) (x - 6)
