What two numbers multiply to 612 and add up to -77?

Here we answer the question: "What two numbers multiply to 612 and add up to -77?"

The answer to your question is:

-68 and -9

Below we illustrate and prove that -68 and -9 multiply to 612 and add up to -77:

-68 × -9 = 612
-68 + -9 = -77

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

x² - 77x + 612 = 0

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

(x - 68 ) (x - 9)

To summarize, since -68 and -9 multiply to 612 and add up -77, you know that the following is true:

x² - 77x + 612 = (x - 68 ) (x - 9)
