Here we answer the question: "What two numbers multiply to -584 and add up to 290?"
The answer to your question is:
-2 and 292
Below we illustrate and prove that -2 and 292 multiply to -584 and add up to 290:
-2 × 292 = -584
-2 + 292 = 290
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 290x - 584 = 0
If so, the solution to factor the quadratic equation above is:
(x - 2 ) (x + 292)
To summarize, since -2 and 292 multiply to -584 and add up 290, you know that the following is true:
x2 + 290x - 584 = (x - 2 ) (x + 292)
