What two numbers multiply to 660 and add up to 223?

Here we answer the question: "What two numbers multiply to 660 and add up to 223?"

The answer to your question is:

3 and 220

Below we illustrate and prove that 3 and 220 multiply to 660 and add up to 223:

3 × 220 = 660
3 + 220 = 223

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

x² + 223x + 660 = 0

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

(x + 3 ) (x + 220)

To summarize, since 3 and 220 multiply to 660 and add up 223, you know that the following is true:

x² + 223x + 660 = (x + 3 ) (x + 220)
