What two numbers multiply to -723 and add up to 722?

Here we answer the question: "What two numbers multiply to -723 and add up to 722?"

The answer to your question is:

-1 and 723

Below we illustrate and prove that -1 and 723 multiply to -723 and add up to 722:

-1 × 723 = -723
-1 + 723 = 722

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

x² + 722x - 723 = 0

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

(x - 1 ) (x + 723)

To summarize, since -1 and 723 multiply to -723 and add up 722, you know that the following is true:

x² + 722x - 723 = (x - 1 ) (x + 723)
