Here we answer the question: "What two numbers multiply to 869 and add up to 870?"

The answer to your question is:

1 and 869

Below we illustrate and prove that 1 and 869 multiply to 869 and add up to 870:

1 × 869 = 869
1 + 869 = 870

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

x² + 870x + 869 = 0

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

(x + 1 ) (x + 869)

To summarize, since 1 and 869 multiply to 869 and add up 870, you know that the following is true:

x² + 870x + 869 = (x + 1 ) (x + 869)
