What two numbers multiply to -936 and add up to 309?

Here we answer the question: "What two numbers multiply to -936 and add up to 309?"

The answer to your question is:

-3 and 312

Below we illustrate and prove that -3 and 312 multiply to -936 and add up to 309:

-3 × 312 = -936
-3 + 312 = 309

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

x² + 309x - 936 = 0

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

(x - 3 ) (x + 312)

To summarize, since -3 and 312 multiply to -936 and add up 309, you know that the following is true:

x² + 309x - 936 = (x - 3 ) (x + 312)
