What two numbers multiply to -560 and add up to 73?

Here we answer the question: "What two numbers multiply to -560 and add up to 73?"

The answer to your question is:

-7 and 80

Below we illustrate and prove that -7 and 80 multiply to -560 and add up to 73:

-7 × 80 = -560
-7 + 80 = 73

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

x² + 73x - 560 = 0

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

(x - 7 ) (x + 80)

To summarize, since -7 and 80 multiply to -560 and add up 73, you know that the following is true:

x² + 73x - 560 = (x - 7 ) (x + 80)
