What two numbers multiply to -805 and add up to 156?

Here we answer the question: "What two numbers multiply to -805 and add up to 156?"

The answer to your question is:

-5 and 161

Below we illustrate and prove that -5 and 161 multiply to -805 and add up to 156:

-5 × 161 = -805
-5 + 161 = 156

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

x² + 156x - 805 = 0

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

(x - 5 ) (x + 161)

To summarize, since -5 and 161 multiply to -805 and add up 156, you know that the following is true:

x² + 156x - 805 = (x - 5 ) (x + 161)
