What two numbers multiply to 858 and add up to -79?

Here we answer the question: "What two numbers multiply to 858 and add up to -79?"

The answer to your question is:

-66 and -13

Below we illustrate and prove that -66 and -13 multiply to 858 and add up to -79:

-66 × -13 = 858
-66 + -13 = -79

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

x² - 79x + 858 = 0

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

(x - 66 ) (x - 13)

To summarize, since -66 and -13 multiply to 858 and add up -79, you know that the following is true:

x² - 79x + 858 = (x - 66 ) (x - 13)
