Here we answer the question: "What two numbers multiply to -690 and add up to 227?"
The answer to your question is:
-3 and 230
Below we illustrate and prove that -3 and 230 multiply to -690 and add up to 227:
-3 × 230 = -690
-3 + 230 = 227
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 227x - 690 = 0
If so, the solution to factor the quadratic equation above is:
(x - 3 ) (x + 230)
To summarize, since -3 and 230 multiply to -690 and add up 227, you know that the following is true:
x2 + 227x - 690 = (x - 3 ) (x + 230)
