What two numbers multiply to 870 and add up to 871?

Here we answer the question: "What two numbers multiply to 870 and add up to 871?"

The answer to your question is:

1 and 870

Below we illustrate and prove that 1 and 870 multiply to 870 and add up to 871:

1 × 870 = 870
1 + 870 = 871

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

x² + 871x + 870 = 0

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

(x + 1 ) (x + 870)

To summarize, since 1 and 870 multiply to 870 and add up 871, you know that the following is true:

x² + 871x + 870 = (x + 1 ) (x + 870)
