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:

-45 and 16

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

-45 × 16 = -720
-45 + 16 = -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 - 45 ) (x + 16)

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

x² - 29x - 720 = (x - 45 ) (x + 16)
