What two numbers multiply to 768 and add up to -64?

Here we answer the question: "What two numbers multiply to 768 and add up to -64?"

The answer to your question is:

-48 and -16

Below we illustrate and prove that -48 and -16 multiply to 768 and add up to -64:

-48 × -16 = 768
-48 + -16 = -64

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

x² - 64x + 768 = 0

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

(x - 48 ) (x - 16)

To summarize, since -48 and -16 multiply to 768 and add up -64, you know that the following is true:

x² - 64x + 768 = (x - 48 ) (x - 16)
