What two numbers multiply to 655 and add up to 656?

Here we answer the question: "What two numbers multiply to 655 and add up to 656?"

The answer to your question is:

1 and 655

Below we illustrate and prove that 1 and 655 multiply to 655 and add up to 656:

1 × 655 = 655
1 + 655 = 656

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

x² + 656x + 655 = 0

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

(x + 1 ) (x + 655)

To summarize, since 1 and 655 multiply to 655 and add up 656, you know that the following is true:

x² + 656x + 655 = (x + 1 ) (x + 655)
