What two numbers multiply to 960 and add up to -79?

Here we answer the question: "What two numbers multiply to 960 and add up to -79?"

The answer to your question is:

-64 and -15

Below we illustrate and prove that -64 and -15 multiply to 960 and add up to -79:

-64 × -15 = 960
-64 + -15 = -79

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

x² - 79x + 960 = 0

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

(x - 64 ) (x - 15)

To summarize, since -64 and -15 multiply to 960 and add up -79, you know that the following is true:

x² - 79x + 960 = (x - 64 ) (x - 15)
