What two numbers multiply to -672 and add up to -4?

Here we answer the question: "What two numbers multiply to -672 and add up to -4?"

The answer to your question is:

-28 and 24

Below we illustrate and prove that -28 and 24 multiply to -672 and add up to -4:

-28 × 24 = -672
-28 + 24 = -4

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

x² - 4x - 672 = 0

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

(x - 28 ) (x + 24)

To summarize, since -28 and 24 multiply to -672 and add up -4, you know that the following is true:

x² - 4x - 672 = (x - 28 ) (x + 24)
