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

The answer to your question is:

2 and 428

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

2 × 428 = 856
2 + 428 = 430

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

x² + 430x + 856 = 0
