What two numbers multiply to -672 and add up to -11?

Here we answer the question: "What two numbers multiply to -672 and add up to -11?"

The answer to your question is:

-32 and 21

Below we illustrate and prove that -32 and 21 multiply to -672 and add up to -11:

-32 × 21 = -672
-32 + 21 = -11

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

x² - 11x - 672 = 0

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

(x - 32 ) (x + 21)

To summarize, since -32 and 21 multiply to -672 and add up -11, you know that the following is true:

x² - 11x - 672 = (x - 32 ) (x + 21)
