What two numbers multiply to 816 and add up to -67?

Here we answer the question: "What two numbers multiply to 816 and add up to -67?"

The answer to your question is:

-51 and -16

Below we illustrate and prove that -51 and -16 multiply to 816 and add up to -67:

-51 × -16 = 816
-51 + -16 = -67

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

x² - 67x + 816 = 0

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

(x - 51 ) (x - 16)

To summarize, since -51 and -16 multiply to 816 and add up -67, you know that the following is true:

x² - 67x + 816 = (x - 51 ) (x - 16)
