What two numbers multiply to 877 and add up to 878?

Here we answer the question: "What two numbers multiply to 877 and add up to 878?"

The answer to your question is:

1 and 877

Below we illustrate and prove that 1 and 877 multiply to 877 and add up to 878:

1 × 877 = 877
1 + 877 = 878

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

x² + 878x + 877 = 0

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

(x + 1 ) (x + 877)

To summarize, since 1 and 877 multiply to 877 and add up 878, you know that the following is true:

x² + 878x + 877 = (x + 1 ) (x + 877)
