Here we answer the question: "What two numbers multiply to -316 and add up to 156?"
The answer to your question is:
-2 and 158
Below we illustrate and prove that -2 and 158 multiply to -316 and add up to 156:
-2 × 158 = -316
-2 + 158 = 156
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 156x - 316 = 0
If so, the solution to factor the quadratic equation above is:
(x - 2 ) (x + 158)
To summarize, since -2 and 158 multiply to -316 and add up 156, you know that the following is true:
x2 + 156x - 316 = (x - 2 ) (x + 158)
