What two numbers multiply to 324 and add up to -36?

Here we answer the question: "What two numbers multiply to 324 and add up to -36?"

The answer to your question is:

-18 and -18

Below we illustrate and prove that -18 and -18 multiply to 324 and add up to -36:

-18 × -18 = 324
-18 + -18 = -36

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

x² - 36x + 324 = 0

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

(x - 18 ) (x - 18)

To summarize, since -18 and -18 multiply to 324 and add up -36, you know that the following is true:

x² - 36x + 324 = (x - 18 ) (x - 18)
