Here we answer the question: "What two numbers multiply to -500 and add up to -5?"
The answer to your question is:
-25 and 20
Below we illustrate and prove that -25 and 20 multiply to -500 and add up to -5:
-25 × 20 = -500
-25 + 20 = -5
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 5x - 500 = 0
If so, the solution to factor the quadratic equation above is:
(x - 25 ) (x + 20)
To summarize, since -25 and 20 multiply to -500 and add up -5, you know that the following is true:
x2 - 5x - 500 = (x - 25 ) (x + 20)
