What two numbers multiply to -697 and add up to 696?

Here we answer the question: "What two numbers multiply to -697 and add up to 696?"

The answer to your question is:

-1 and 697

Below we illustrate and prove that -1 and 697 multiply to -697 and add up to 696:

-1 × 697 = -697
-1 + 697 = 696

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

x² + 696x - 697 = 0

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

(x - 1 ) (x + 697)

To summarize, since -1 and 697 multiply to -697 and add up 696, you know that the following is true:

x² + 696x - 697 = (x - 1 ) (x + 697)
