What two numbers multiply to -660 and add up to -161?

Here we answer the question: "What two numbers multiply to -660 and add up to -161?"

The answer to your question is:

-165 and 4

Below we illustrate and prove that -165 and 4 multiply to -660 and add up to -161:

-165 × 4 = -660
-165 + 4 = -161

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

x² - 161x - 660 = 0

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

(x - 165 ) (x + 4)

To summarize, since -165 and 4 multiply to -660 and add up -161, you know that the following is true:

x² - 161x - 660 = (x - 165 ) (x + 4)
