What two numbers multiply to -668 and add up to 163?

Here we answer the question: "What two numbers multiply to -668 and add up to 163?"

The answer to your question is:

-4 and 167

Below we illustrate and prove that -4 and 167 multiply to -668 and add up to 163:

-4 × 167 = -668
-4 + 167 = 163

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

x² + 163x - 668 = 0

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

(x - 4 ) (x + 167)

To summarize, since -4 and 167 multiply to -668 and add up 163, you know that the following is true:

x² + 163x - 668 = (x - 4 ) (x + 167)
