What two numbers multiply to -207 and add up to 66?

Here we answer the question: "What two numbers multiply to -207 and add up to 66?"

The answer to your question is:

-3 and 69

Below we illustrate and prove that -3 and 69 multiply to -207 and add up to 66:

-3 × 69 = -207
-3 + 69 = 66

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

x² + 66x - 207 = 0

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

(x - 3 ) (x + 69)

To summarize, since -3 and 69 multiply to -207 and add up 66, you know that the following is true:

x² + 66x - 207 = (x - 3 ) (x + 69)
