Here we answer the question: "What two numbers multiply to -345 and add up to 344?"
The answer to your question is:
-1 and 345
Below we illustrate and prove that -1 and 345 multiply to -345 and add up to 344:
-1 × 345 = -345
-1 + 345 = 344
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 344x - 345 = 0
If so, the solution to factor the quadratic equation above is:
(x - 1 ) (x + 345)
To summarize, since -1 and 345 multiply to -345 and add up 344, you know that the following is true:
x2 + 344x - 345 = (x - 1 ) (x + 345)
