Here we answer the question: "What two numbers multiply to 510 and add up to -47?"
The answer to your question is:
-30 and -17
Below we illustrate and prove that -30 and -17 multiply to 510 and add up to -47:
-30 × -17 = 510
-30 + -17 = -47
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 47x + 510 = 0
If so, the solution to factor the quadratic equation above is:
(x - 30 ) (x - 17)
To summarize, since -30 and -17 multiply to 510 and add up -47, you know that the following is true:
x2 - 47x + 510 = (x - 30 ) (x - 17)
