What two numbers multiply to -180 and add up to -8?

Here we answer the question: "What two numbers multiply to -180 and add up to -8?"

The answer to your question is:

-18 and 10

Below we illustrate and prove that -18 and 10 multiply to -180 and add up to -8:

-18 × 10 = -180
-18 + 10 = -8

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

x² - 8x - 180 = 0

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

(x - 18 ) (x + 10)

To summarize, since -18 and 10 multiply to -180 and add up -8, you know that the following is true:

x² - 8x - 180 = (x - 18 ) (x + 10)
