What two numbers multiply to 324 and add up to -45?

Here we answer the question: "What two numbers multiply to 324 and add up to -45?"

The answer to your question is:

-36 and -9

Below we illustrate and prove that -36 and -9 multiply to 324 and add up to -45:

-36 × -9 = 324
-36 + -9 = -45

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

x² - 45x + 324 = 0

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

(x - 36 ) (x - 9)

To summarize, since -36 and -9 multiply to 324 and add up -45, you know that the following is true:

x² - 45x + 324 = (x - 36 ) (x - 9)
