Here we answer the question: "What two numbers multiply to -712 and add up to -354?"
The answer to your question is:
-356 and 2
Below we illustrate and prove that -356 and 2 multiply to -712 and add up to -354:
-356 × 2 = -712
-356 + 2 = -354
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 354x - 712 = 0
If so, the solution to factor the quadratic equation above is:
(x - 356 ) (x + 2)
To summarize, since -356 and 2 multiply to -712 and add up -354, you know that the following is true:
x2 - 354x - 712 = (x - 356 ) (x + 2)
