What two numbers multiply to 780 and add up to 781?

Here we answer the question: "What two numbers multiply to 780 and add up to 781?"

The answer to your question is:

1 and 780

Below we illustrate and prove that 1 and 780 multiply to 780 and add up to 781:

1 × 780 = 780
1 + 780 = 781

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

x² + 781x + 780 = 0

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

(x + 1 ) (x + 780)

To summarize, since 1 and 780 multiply to 780 and add up 781, you know that the following is true:

x² + 781x + 780 = (x + 1 ) (x + 780)
