What two numbers multiply to -936 and add up to 66?

Here we answer the question: "What two numbers multiply to -936 and add up to 66?"

The answer to your question is:

-12 and 78

Below we illustrate and prove that -12 and 78 multiply to -936 and add up to 66:

-12 × 78 = -936
-12 + 78 = 66

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

x² + 66x - 936 = 0

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

(x - 12 ) (x + 78)

To summarize, since -12 and 78 multiply to -936 and add up 66, you know that the following is true:

x² + 66x - 936 = (x - 12 ) (x + 78)
