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:

-8 and 17

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

-8 × 17 = -136
-8 + 17 = 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 - 8 ) (x + 17)

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

x² + 9x - 136 = (x - 8 ) (x + 17)
