What two numbers multiply to -724 and add up to 723?

Here we answer the question: "What two numbers multiply to -724 and add up to 723?"

The answer to your question is:

-1 and 724

Below we illustrate and prove that -1 and 724 multiply to -724 and add up to 723:

-1 × 724 = -724
-1 + 724 = 723

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

x² + 723x - 724 = 0

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

(x - 1 ) (x + 724)

To summarize, since -1 and 724 multiply to -724 and add up 723, you know that the following is true:

x² + 723x - 724 = (x - 1 ) (x + 724)
