What two numbers multiply to 816 and add up to -142?

Here we answer the question: "What two numbers multiply to 816 and add up to -142?"

The answer to your question is:

-136 and -6

Below we illustrate and prove that -136 and -6 multiply to 816 and add up to -142:

-136 × -6 = 816
-136 + -6 = -142

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

x² - 142x + 816 = 0

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

(x - 136 ) (x - 6)

To summarize, since -136 and -6 multiply to 816 and add up -142, you know that the following is true:

x² - 142x + 816 = (x - 136 ) (x - 6)
