What two numbers multiply to -580 and add up to 288?

Here we answer the question: "What two numbers multiply to -580 and add up to 288?"

The answer to your question is:

-2 and 290

Below we illustrate and prove that -2 and 290 multiply to -580 and add up to 288:

-2 × 290 = -580
-2 + 290 = 288

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

x² + 288x - 580 = 0

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

(x - 2 ) (x + 290)

To summarize, since -2 and 290 multiply to -580 and add up 288, you know that the following is true:

x² + 288x - 580 = (x - 2 ) (x + 290)
