What two numbers multiply to 312 and add up to -47?

Here we answer the question: "What two numbers multiply to 312 and add up to -47?"

The answer to your question is:

-39 and -8

Below we illustrate and prove that -39 and -8 multiply to 312 and add up to -47:

-39 × -8 = 312
-39 + -8 = -47

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

x² - 47x + 312 = 0

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

(x - 39 ) (x - 8)

To summarize, since -39 and -8 multiply to 312 and add up -47, you know that the following is true:

x² - 47x + 312 = (x - 39 ) (x - 8)
