Here we answer the question: "What two numbers multiply to -248 and add up to 122?"
The answer to your question is:
-2 and 124
Below we illustrate and prove that -2 and 124 multiply to -248 and add up to 122:
-2 × 124 = -248
-2 + 124 = 122
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 122x - 248 = 0
If so, the solution to factor the quadratic equation above is:
(x - 2 ) (x + 124)
To summarize, since -2 and 124 multiply to -248 and add up 122, you know that the following is true:
x2 + 122x - 248 = (x - 2 ) (x + 124)
