Here we answer the question: "What two numbers multiply to -318 and add up to 47?"
The answer to your question is:
-6 and 53
Below we illustrate and prove that -6 and 53 multiply to -318 and add up to 47:
-6 × 53 = -318
-6 + 53 = 47
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 47x - 318 = 0
If so, the solution to factor the quadratic equation above is:
(x - 6 ) (x + 53)
To summarize, since -6 and 53 multiply to -318 and add up 47, you know that the following is true:
x2 + 47x - 318 = (x - 6 ) (x + 53)
