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:

-8 and 26

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

-8 × 26 = -208
-8 + 26 = 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 - 8 ) (x + 26)

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

x² + 18x - 208 = (x - 8 ) (x + 26)
