What two numbers multiply to 960 and add up to -128?

Here we answer the question: "What two numbers multiply to 960 and add up to -128?"

The answer to your question is:

-120 and -8

Below we illustrate and prove that -120 and -8 multiply to 960 and add up to -128:

-120 × -8 = 960
-120 + -8 = -128

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

x² - 128x + 960 = 0

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

(x - 120 ) (x - 8)

To summarize, since -120 and -8 multiply to 960 and add up -128, you know that the following is true:

x² - 128x + 960 = (x - 120 ) (x - 8)
