What two numbers multiply to -864 and add up to 430?

Here we answer the question: "What two numbers multiply to -864 and add up to 430?"

The answer to your question is:

-2 and 432

Below we illustrate and prove that -2 and 432 multiply to -864 and add up to 430:

-2 × 432 = -864
-2 + 432 = 430

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

x² + 430x - 864 = 0

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

(x - 2 ) (x + 432)

To summarize, since -2 and 432 multiply to -864 and add up 430, you know that the following is true:

x² + 430x - 864 = (x - 2 ) (x + 432)
