What two numbers multiply to 646 and add up to 325?

Here we answer the question: "What two numbers multiply to 646 and add up to 325?"

The answer to your question is:

2 and 323

Below we illustrate and prove that 2 and 323 multiply to 646 and add up to 325:

2 × 323 = 646
2 + 323 = 325

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

x² + 325x + 646 = 0

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

(x + 2 ) (x + 323)

To summarize, since 2 and 323 multiply to 646 and add up 325, you know that the following is true:

x² + 325x + 646 = (x + 2 ) (x + 323)
