What two numbers multiply to -684 and add up to -45?

Here we answer the question: "What two numbers multiply to -684 and add up to -45?"

The answer to your question is:

-57 and 12

Below we illustrate and prove that -57 and 12 multiply to -684 and add up to -45:

-57 × 12 = -684
-57 + 12 = -45

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

x² - 45x - 684 = 0

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

(x - 57 ) (x + 12)

To summarize, since -57 and 12 multiply to -684 and add up -45, you know that the following is true:

x² - 45x - 684 = (x - 57 ) (x + 12)
