What two numbers multiply to 605 and add up to -66?

Here we answer the question: "What two numbers multiply to 605 and add up to -66?"

The answer to your question is:

-55 and -11

Below we illustrate and prove that -55 and -11 multiply to 605 and add up to -66:

-55 × -11 = 605
-55 + -11 = -66

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

x² - 66x + 605 = 0

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

(x - 55 ) (x - 11)

To summarize, since -55 and -11 multiply to 605 and add up -66, you know that the following is true:

x² - 66x + 605 = (x - 55 ) (x - 11)
