What two numbers multiply to 656 and add up to -330?

Here we answer the question: "What two numbers multiply to 656 and add up to -330?"

The answer to your question is:

-328 and -2

Below we illustrate and prove that -328 and -2 multiply to 656 and add up to -330:

-328 × -2 = 656
-328 + -2 = -330

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

x² - 330x + 656 = 0

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

(x - 328 ) (x - 2)

To summarize, since -328 and -2 multiply to 656 and add up -330, you know that the following is true:

x² - 330x + 656 = (x - 328 ) (x - 2)
