What two numbers multiply to 336 and add up to -40?

Here we answer the question: "What two numbers multiply to 336 and add up to -40?"

The answer to your question is:

-28 and -12

Below we illustrate and prove that -28 and -12 multiply to 336 and add up to -40:

-28 × -12 = 336
-28 + -12 = -40

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

x² - 40x + 336 = 0

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

(x - 28 ) (x - 12)

To summarize, since -28 and -12 multiply to 336 and add up -40, you know that the following is true:

x² - 40x + 336 = (x - 28 ) (x - 12)
