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)
