What two numbers multiply to 879 and add up to 880?

Here we answer the question: "What two numbers multiply to 879 and add up to 880?"

The answer to your question is:

1 and 879

Below we illustrate and prove that 1 and 879 multiply to 879 and add up to 880:

1 × 879 = 879
1 + 879 = 880

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

x² + 880x + 879 = 0

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

(x + 1 ) (x + 879)

To summarize, since 1 and 879 multiply to 879 and add up 880, you know that the following is true:

x² + 880x + 879 = (x + 1 ) (x + 879)
