Here we answer the question: "What two numbers multiply to -504 and add up to 10?"
The answer to your question is:
-18 and 28
Below we illustrate and prove that -18 and 28 multiply to -504 and add up to 10:
-18 × 28 = -504
-18 + 28 = 10
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 10x - 504 = 0
If so, the solution to factor the quadratic equation above is:
(x - 18 ) (x + 28)
To summarize, since -18 and 28 multiply to -504 and add up 10, you know that the following is true:
x2 + 10x - 504 = (x - 18 ) (x + 28)
