What two numbers multiply to 670 and add up to 671?

Here we answer the question: "What two numbers multiply to 670 and add up to 671?"

The answer to your question is:

1 and 670

Below we illustrate and prove that 1 and 670 multiply to 670 and add up to 671:

1 × 670 = 670
1 + 670 = 671

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

x² + 671x + 670 = 0

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

(x + 1 ) (x + 670)

To summarize, since 1 and 670 multiply to 670 and add up 671, you know that the following is true:

x² + 671x + 670 = (x + 1 ) (x + 670)
