What two numbers multiply to 324 and add up to 111?

Here we answer the question: "What two numbers multiply to 324 and add up to 111?"

The answer to your question is:

3 and 108

Below we illustrate and prove that 3 and 108 multiply to 324 and add up to 111:

3 × 108 = 324
3 + 108 = 111

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

x² + 111x + 324 = 0

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

(x + 3 ) (x + 108)

To summarize, since 3 and 108 multiply to 324 and add up 111, you know that the following is true:

x² + 111x + 324 = (x + 3 ) (x + 108)
