What two numbers multiply to -540 and add up to -51?

Here we answer the question: "What two numbers multiply to -540 and add up to -51?"

The answer to your question is:

-60 and 9

Below we illustrate and prove that -60 and 9 multiply to -540 and add up to -51:

-60 × 9 = -540
-60 + 9 = -51

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

x² - 51x - 540 = 0

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

(x - 60 ) (x + 9)

To summarize, since -60 and 9 multiply to -540 and add up -51, you know that the following is true:

x² - 51x - 540 = (x - 60 ) (x + 9)
