What two numbers multiply to -660 and add up to 29?

Here we answer the question: "What two numbers multiply to -660 and add up to 29?"

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 29:

-15 × 44 = -660
-15 + 44 = 29

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

x² + 29x - 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 29, you know that the following is true:

x² + 29x - 660 = (x - 15 ) (x + 44)
