What two numbers multiply to -700 and add up to 699?

Here we answer the question: "What two numbers multiply to -700 and add up to 699?"

The answer to your question is:

-1 and 700

Below we illustrate and prove that -1 and 700 multiply to -700 and add up to 699:

-1 × 700 = -700
-1 + 700 = 699

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

x² + 699x - 700 = 0

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

(x - 1 ) (x + 700)

To summarize, since -1 and 700 multiply to -700 and add up 699, you know that the following is true:

x² + 699x - 700 = (x - 1 ) (x + 700)
