What two numbers multiply to -699 and add up to 698?

Here we answer the question: "What two numbers multiply to -699 and add up to 698?"

The answer to your question is:

-1 and 699

Below we illustrate and prove that -1 and 699 multiply to -699 and add up to 698:

-1 × 699 = -699
-1 + 699 = 698

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

x² + 698x - 699 = 0

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

(x - 1 ) (x + 699)

To summarize, since -1 and 699 multiply to -699 and add up 698, you know that the following is true:

x² + 698x - 699 = (x - 1 ) (x + 699)
