What two numbers multiply to -48 and add up to -8?

Here we answer the question: "What two numbers multiply to -48 and add up to -8?"

The answer to your question is:

-12 and 4

Below we illustrate and prove that -12 and 4 multiply to -48 and add up to -8:

-12 × 4 = -48
-12 + 4 = -8

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

x² - 8x - 48 = 0

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

(x - 12 ) (x + 4)

To summarize, since -12 and 4 multiply to -48 and add up -8, you know that the following is true:

x² - 8x - 48 = (x - 12 ) (x + 4)
