What two numbers multiply to 48 and add up to -16?

Here we answer the question: "What two numbers multiply to 48 and add up to -16?"

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 -16:

-12 × -4 = 48
-12 + -4 = -16

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

x² - 16x + 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 -16, you know that the following is true:

x² - 16x + 48 = (x - 12 ) (x - 4)
