Here we answer the question: "What two numbers multiply to 974 and add up to 489?"
The answer to your question is:
2 and 487
Below we illustrate and prove that 2 and 487 multiply to 974 and add up to 489:
2 × 487 = 974
2 + 487 = 489
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 489x + 974 = 0
If so, the solution to factor the quadratic equation above is:
(x + 2 ) (x + 487)
To summarize, since 2 and 487 multiply to 974 and add up 489, you know that the following is true:
x2 + 489x + 974 = (x + 2 ) (x + 487)
