What two numbers multiply to -664 and add up to 162?

Here we answer the question: "What two numbers multiply to -664 and add up to 162?"

The answer to your question is:

-4 and 166

Below we illustrate and prove that -4 and 166 multiply to -664 and add up to 162:

-4 × 166 = -664
-4 + 166 = 162

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

x² + 162x - 664 = 0

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

(x - 4 ) (x + 166)

To summarize, since -4 and 166 multiply to -664 and add up 162, you know that the following is true:

x² + 162x - 664 = (x - 4 ) (x + 166)
