What two numbers multiply to 960 and add up to -64?

Here we answer the question: "What two numbers multiply to 960 and add up to -64?"

The answer to your question is:

-40 and -24

Below we illustrate and prove that -40 and -24 multiply to 960 and add up to -64:

-40 × -24 = 960
-40 + -24 = -64

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

x² - 64x + 960 = 0

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

(x - 40 ) (x - 24)

To summarize, since -40 and -24 multiply to 960 and add up -64, you know that the following is true:

x² - 64x + 960 = (x - 40 ) (x - 24)
