What two numbers multiply to 660 and add up to 59?

Here we answer the question: "What two numbers multiply to 660 and add up to 59?"

The answer to your question is:

15 and 44

Below we illustrate and prove that 15 and 44 multiply to 660 and add up to 59:

15 × 44 = 660
15 + 44 = 59

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

x² + 59x + 660 = 0

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

(x + 15 ) (x + 44)

To summarize, since 15 and 44 multiply to 660 and add up 59, you know that the following is true:

x² + 59x + 660 = (x + 15 ) (x + 44)
