What two numbers multiply to 667 and add up to 668?

Here we answer the question: "What two numbers multiply to 667 and add up to 668?"

The answer to your question is:

1 and 667

Below we illustrate and prove that 1 and 667 multiply to 667 and add up to 668:

1 × 667 = 667
1 + 667 = 668

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

x² + 668x + 667 = 0

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

(x + 1 ) (x + 667)

To summarize, since 1 and 667 multiply to 667 and add up 668, you know that the following is true:

x² + 668x + 667 = (x + 1 ) (x + 667)
