What two numbers multiply to -656 and add up to 326?

Here we answer the question: "What two numbers multiply to -656 and add up to 326?"

The answer to your question is:

-2 and 328

Below we illustrate and prove that -2 and 328 multiply to -656 and add up to 326:

-2 × 328 = -656
-2 + 328 = 326

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

x² + 326x - 656 = 0

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

(x - 2 ) (x + 328)

To summarize, since -2 and 328 multiply to -656 and add up 326, you know that the following is true:

x² + 326x - 656 = (x - 2 ) (x + 328)
