What two numbers multiply to -208 and add up to 207?

Here we answer the question: "What two numbers multiply to -208 and add up to 207?"

The answer to your question is:

-1 and 208

Below we illustrate and prove that -1 and 208 multiply to -208 and add up to 207:

-1 × 208 = -208
-1 + 208 = 207

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

x² + 207x - 208 = 0

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

(x - 1 ) (x + 208)

To summarize, since -1 and 208 multiply to -208 and add up 207, you know that the following is true:

x² + 207x - 208 = (x - 1 ) (x + 208)
