What two numbers multiply to -430 and add up to 429?

Here we answer the question: "What two numbers multiply to -430 and add up to 429?"

The answer to your question is:

-1 and 430

Below we illustrate and prove that -1 and 430 multiply to -430 and add up to 429:

-1 × 430 = -430
-1 + 430 = 429

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

x² + 429x - 430 = 0

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

(x - 1 ) (x + 430)

To summarize, since -1 and 430 multiply to -430 and add up 429, you know that the following is true:

x² + 429x - 430 = (x - 1 ) (x + 430)
