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:

-21 and 32

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

-21 × 32 = -672
-21 + 32 = 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 - 21 ) (x + 32)

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

x² + 11x - 672 = (x - 21 ) (x + 32)
