What two numbers multiply to 878 and add up to 879?

Here we answer the question: "What two numbers multiply to 878 and add up to 879?"

The answer to your question is:

1 and 878

Below we illustrate and prove that 1 and 878 multiply to 878 and add up to 879:

1 × 878 = 878
1 + 878 = 879

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

x² + 879x + 878 = 0

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

(x + 1 ) (x + 878)

To summarize, since 1 and 878 multiply to 878 and add up 879, you know that the following is true:

x² + 879x + 878 = (x + 1 ) (x + 878)
