What two numbers multiply to -816 and add up to 130?

Here we answer the question: "What two numbers multiply to -816 and add up to 130?"

The answer to your question is:

-6 and 136

Below we illustrate and prove that -6 and 136 multiply to -816 and add up to 130:

-6 × 136 = -816
-6 + 136 = 130

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

x² + 130x - 816 = 0
