What two numbers multiply to -720 and add up to 62?

Here we answer the question: "What two numbers multiply to -720 and add up to 62?"

The answer to your question is:

-10 and 72

Below we illustrate and prove that -10 and 72 multiply to -720 and add up to 62:

-10 × 72 = -720
-10 + 72 = 62

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

x² + 62x - 720 = 0

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

(x - 10 ) (x + 72)

To summarize, since -10 and 72 multiply to -720 and add up 62, you know that the following is true:

x² + 62x - 720 = (x - 10 ) (x + 72)
