Here we answer the question: "What two numbers multiply to -708 and add up to 47?"
The answer to your question is:
-12 and 59
Below we illustrate and prove that -12 and 59 multiply to -708 and add up to 47:
-12 × 59 = -708
-12 + 59 = 47
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 47x - 708 = 0
If so, the solution to factor the quadratic equation above is:
(x - 12 ) (x + 59)
To summarize, since -12 and 59 multiply to -708 and add up 47, you know that the following is true:
x2 + 47x - 708 = (x - 12 ) (x + 59)
