What two numbers multiply to -136 and add up to -9?

Here we answer the question: "What two numbers multiply to -136 and add up to -9?"

The answer to your question is:

-17 and 8

Below we illustrate and prove that -17 and 8 multiply to -136 and add up to -9:

-17 × 8 = -136
-17 + 8 = -9

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

x² - 9x - 136 = 0

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

(x - 17 ) (x + 8)

To summarize, since -17 and 8 multiply to -136 and add up -9, you know that the following is true:

x² - 9x - 136 = (x - 17 ) (x + 8)
