Here we answer the question: "What two numbers multiply to 654 and add up to 221?"
The answer to your question is:
3 and 218
Below we illustrate and prove that 3 and 218 multiply to 654 and add up to 221:
3 × 218 = 654
3 + 218 = 221
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 221x + 654 = 0
If so, the solution to factor the quadratic equation above is:
(x + 3 ) (x + 218)
To summarize, since 3 and 218 multiply to 654 and add up 221, you know that the following is true:
x2 + 221x + 654 = (x + 3 ) (x + 218)
