What two numbers multiply to 636 and add up to 320?

Here we answer the question: "What two numbers multiply to 636 and add up to 320?"

The answer to your question is:

2 and 318

Below we illustrate and prove that 2 and 318 multiply to 636 and add up to 320:

2 × 318 = 636
2 + 318 = 320

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

x² + 320x + 636 = 0

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

(x + 2 ) (x + 318)

To summarize, since 2 and 318 multiply to 636 and add up 320, you know that the following is true:

x² + 320x + 636 = (x + 2 ) (x + 318)
