Here we answer the question: "What two numbers multiply to 492 and add up to 127?"
The answer to your question is:
4 and 123
Below we illustrate and prove that 4 and 123 multiply to 492 and add up to 127:
4 × 123 = 492
4 + 123 = 127
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 127x + 492 = 0
If so, the solution to factor the quadratic equation above is:
(x + 4 ) (x + 123)
To summarize, since 4 and 123 multiply to 492 and add up 127, you know that the following is true:
x2 + 127x + 492 = (x + 4 ) (x + 123)
