What two numbers multiply to -720 and add up to 29?

Here we answer the question: "What two numbers multiply to -720 and add up to 29?"

The answer to your question is:

-16 and 45

Below we illustrate and prove that -16 and 45 multiply to -720 and add up to 29:

-16 × 45 = -720
-16 + 45 = 29

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

x² + 29x - 720 = 0

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

(x - 16 ) (x + 45)

To summarize, since -16 and 45 multiply to -720 and add up 29, you know that the following is true:

x² + 29x - 720 = (x - 16 ) (x + 45)
