What two numbers multiply to 671 and add up to -72?

Here we answer the question: "What two numbers multiply to 671 and add up to -72?"

The answer to your question is:

-61 and -11

Below we illustrate and prove that -61 and -11 multiply to 671 and add up to -72:

-61 × -11 = 671
-61 + -11 = -72

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

x² - 72x + 671 = 0

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

(x - 61 ) (x - 11)

To summarize, since -61 and -11 multiply to 671 and add up -72, you know that the following is true:

x² - 72x + 671 = (x - 61 ) (x - 11)
