What two numbers multiply to -945 and add up to 312?

Here we answer the question: "What two numbers multiply to -945 and add up to 312?"

The answer to your question is:

-3 and 315

Below we illustrate and prove that -3 and 315 multiply to -945 and add up to 312:

-3 × 315 = -945
-3 + 315 = 312

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

x² + 312x - 945 = 0

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

(x - 3 ) (x + 315)

To summarize, since -3 and 315 multiply to -945 and add up 312, you know that the following is true:

x² + 312x - 945 = (x - 3 ) (x + 315)
