What two numbers multiply to -324 and add up to 0?

Here we answer the question: "What two numbers multiply to -324 and add up to 0?"

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 0:

-18 × 18 = -324
-18 + 18 = 0

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

x² + 0x - 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 0, you know that the following is true:

x² + 0x - 324 = (x - 18 ) (x + 18)
