What two numbers multiply to 644 and add up to 324?

Here we answer the question: "What two numbers multiply to 644 and add up to 324?"

The answer to your question is:

2 and 322

Below we illustrate and prove that 2 and 322 multiply to 644 and add up to 324:

2 × 322 = 644
2 + 322 = 324

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

x² + 324x + 644 = 0

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

(x + 2 ) (x + 322)

To summarize, since 2 and 322 multiply to 644 and add up 324, you know that the following is true:

x² + 324x + 644 = (x + 2 ) (x + 322)
