What two numbers multiply to -730 and add up to 729?

Here we answer the question: "What two numbers multiply to -730 and add up to 729?"

The answer to your question is:

-1 and 730

Below we illustrate and prove that -1 and 730 multiply to -730 and add up to 729:

-1 × 730 = -730
-1 + 730 = 729

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

x² + 729x - 730 = 0

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

(x - 1 ) (x + 730)

To summarize, since -1 and 730 multiply to -730 and add up 729, you know that the following is true:

x² + 729x - 730 = (x - 1 ) (x + 730)
