What two numbers multiply to 28 and add up to -16?

Here we answer the question: "What two numbers multiply to 28 and add up to -16?"

The answer to your question is:

-14 and -2

Below we illustrate and prove that -14 and -2 multiply to 28 and add up to -16:

-14 × -2 = 28
-14 + -2 = -16

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

x² - 16x + 28 = 0

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

(x - 14 ) (x - 2)

To summarize, since -14 and -2 multiply to 28 and add up -16, you know that the following is true:

x² - 16x + 28 = (x - 14 ) (x - 2)
