What two numbers multiply to 864 and add up to 865?

Here we answer the question: "What two numbers multiply to 864 and add up to 865?"

The answer to your question is:

1 and 864

Below we illustrate and prove that 1 and 864 multiply to 864 and add up to 865:

1 × 864 = 864
1 + 864 = 865

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

x² + 865x + 864 = 0

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

(x + 1 ) (x + 864)

To summarize, since 1 and 864 multiply to 864 and add up 865, you know that the following is true:

x² + 865x + 864 = (x + 1 ) (x + 864)
