What two numbers multiply to 660 and add up to -53?

Here we answer the question: "What two numbers multiply to 660 and add up to -53?"

The answer to your question is:

-33 and -20

Below we illustrate and prove that -33 and -20 multiply to 660 and add up to -53:

-33 × -20 = 660
-33 + -20 = -53

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

x² - 53x + 660 = 0

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

(x - 33 ) (x - 20)

To summarize, since -33 and -20 multiply to 660 and add up -53, you know that the following is true:

x² - 53x + 660 = (x - 33 ) (x - 20)
