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:

20 and 33

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

20 × 33 = 660
20 + 33 = 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 + 20 ) (x + 33)

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

x² + 53x + 660 = (x + 20 ) (x + 33)
