What two numbers multiply to 448 and add up to -64?

Here we answer the question: "What two numbers multiply to 448 and add up to -64?"

The answer to your question is:

-56 and -8

Below we illustrate and prove that -56 and -8 multiply to 448 and add up to -64:

-56 × -8 = 448
-56 + -8 = -64

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

x² - 64x + 448 = 0

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

(x - 56 ) (x - 8)

To summarize, since -56 and -8 multiply to 448 and add up -64, you know that the following is true:

x² - 64x + 448 = (x - 56 ) (x - 8)
