What two numbers multiply to 648 and add up to 326?

Here we answer the question: "What two numbers multiply to 648 and add up to 326?"

The answer to your question is:

2 and 324

Below we illustrate and prove that 2 and 324 multiply to 648 and add up to 326:

2 × 324 = 648
2 + 324 = 326

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

x² + 326x + 648 = 0

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

(x + 2 ) (x + 324)

To summarize, since 2 and 324 multiply to 648 and add up 326, you know that the following is true:

x² + 326x + 648 = (x + 2 ) (x + 324)
