Here we answer the question: "What two numbers multiply to 812 and add up to -57?"

The answer to your question is:

-29 and -28

Below we illustrate and prove that -29 and -28 multiply to 812 and add up to -57:

-29 × -28 = 812
-29 + -28 = -57

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

x² - 57x + 812 = 0

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

(x - 29 ) (x - 28)

To summarize, since -29 and -28 multiply to 812 and add up -57, you know that the following is true:

x² - 57x + 812 = (x - 29 ) (x - 28)
