What two numbers multiply to 189 and add up to -66?

Here we answer the question: "What two numbers multiply to 189 and add up to -66?"

The answer to your question is:

-63 and -3

Below we illustrate and prove that -63 and -3 multiply to 189 and add up to -66:

-63 × -3 = 189
-63 + -3 = -66

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

x² - 66x + 189 = 0

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

(x - 63 ) (x - 3)

To summarize, since -63 and -3 multiply to 189 and add up -66, you know that the following is true:

x² - 66x + 189 = (x - 63 ) (x - 3)
