What two numbers multiply to 670 and add up to -77?

Here we answer the question: "What two numbers multiply to 670 and add up to -77?"

The answer to your question is:

-67 and -10

Below we illustrate and prove that -67 and -10 multiply to 670 and add up to -77:

-67 × -10 = 670
-67 + -10 = -77

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

x² - 77x + 670 = 0

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

(x - 67 ) (x - 10)

To summarize, since -67 and -10 multiply to 670 and add up -77, you know that the following is true:

x² - 77x + 670 = (x - 67 ) (x - 10)
