What two numbers multiply to 960 and add up to -961?

Here we answer the question: "What two numbers multiply to 960 and add up to -961?"

The answer to your question is:

-960 and -1

Below we illustrate and prove that -960 and -1 multiply to 960 and add up to -961:

-960 × -1 = 960
-960 + -1 = -961

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

x² - 961x + 960 = 0

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

(x - 960 ) (x - 1)

To summarize, since -960 and -1 multiply to 960 and add up -961, you know that the following is true:

x² - 961x + 960 = (x - 960 ) (x - 1)
