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:

-700 and 1

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

-700 × 1 = -700
-700 + 1 = -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 - 700 ) (x + 1)

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

x² - 699x - 700 = (x - 700 ) (x + 1)
