Here we answer the question: "What two numbers multiply to 518 and add up to 519?"
The answer to your question is:
1 and 518
Below we illustrate and prove that 1 and 518 multiply to 518 and add up to 519:
1 × 518 = 518
1 + 518 = 519
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 519x + 518 = 0
If so, the solution to factor the quadratic equation above is:
(x + 1 ) (x + 518)
To summarize, since 1 and 518 multiply to 518 and add up 519, you know that the following is true:
x2 + 519x + 518 = (x + 1 ) (x + 518)
