What two numbers multiply to 856 and add up to -430?

Here we answer the question: "What two numbers multiply to 856 and add up to -430?"

The answer to your question is:

-428 and -2

Below we illustrate and prove that -428 and -2 multiply to 856 and add up to -430:

-428 × -2 = 856
-428 + -2 = -430

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

x² - 430x + 856 = 0

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

(x - 428 ) (x - 2)

To summarize, since -428 and -2 multiply to 856 and add up -430, you know that the following is true:

x² - 430x + 856 = (x - 428 ) (x - 2)
