What two numbers multiply to -153 and add up to -8?

Here we answer the question: "What two numbers multiply to -153 and add up to -8?"

The answer to your question is:

-17 and 9

Below we illustrate and prove that -17 and 9 multiply to -153 and add up to -8:

-17 × 9 = -153
-17 + 9 = -8

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

x² - 8x - 153 = 0

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

(x - 17 ) (x + 9)

To summarize, since -17 and 9 multiply to -153 and add up -8, you know that the following is true:

x² - 8x - 153 = (x - 17 ) (x + 9)
