What two numbers multiply to -675 and add up to -66?

Here we answer the question: "What two numbers multiply to -675 and add up to -66?"

The answer to your question is:

-75 and 9

Below we illustrate and prove that -75 and 9 multiply to -675 and add up to -66:

-75 × 9 = -675
-75 + 9 = -66

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

x² - 66x - 675 = 0

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

(x - 75 ) (x + 9)

To summarize, since -75 and 9 multiply to -675 and add up -66, you know that the following is true:

x² - 66x - 675 = (x - 75 ) (x + 9)
