What two numbers multiply to 648 and add up to -326?

Here we answer the question: "What two numbers multiply to 648 and add up to -326?"

The answer to your question is:

-324 and -2

Below we illustrate and prove that -324 and -2 multiply to 648 and add up to -326:

-324 × -2 = 648
-324 + -2 = -326

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

x² - 326x + 648 = 0

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

(x - 324 ) (x - 2)

To summarize, since -324 and -2 multiply to 648 and add up -326, you know that the following is true:

x² - 326x + 648 = (x - 324 ) (x - 2)
