What two numbers multiply to -672 and add up to 164?

Here we answer the question: "What two numbers multiply to -672 and add up to 164?"

The answer to your question is:

-4 and 168

Below we illustrate and prove that -4 and 168 multiply to -672 and add up to 164:

-4 × 168 = -672
-4 + 168 = 164

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

x² + 164x - 672 = 0

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

(x - 4 ) (x + 168)

To summarize, since -4 and 168 multiply to -672 and add up 164, you know that the following is true:

x² + 164x - 672 = (x - 4 ) (x + 168)
