What two numbers multiply to -208 and add up to -18?

Here we answer the question: "What two numbers multiply to -208 and add up to -18?"

The answer to your question is:

-26 and 8

Below we illustrate and prove that -26 and 8 multiply to -208 and add up to -18:

-26 × 8 = -208
-26 + 8 = -18

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

x² - 18x - 208 = 0

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

(x - 26 ) (x + 8)

To summarize, since -26 and 8 multiply to -208 and add up -18, you know that the following is true:

x² - 18x - 208 = (x - 26 ) (x + 8)
