Here we answer the question: "What two numbers multiply to 814 and add up to 815?"
The answer to your question is:
1 and 814
Below we illustrate and prove that 1 and 814 multiply to 814 and add up to 815:
1 × 814 = 814
1 + 814 = 815
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 815x + 814 = 0
If so, the solution to factor the quadratic equation above is:
(x + 1 ) (x + 814)
To summarize, since 1 and 814 multiply to 814 and add up 815, you know that the following is true:
x2 + 815x + 814 = (x + 1 ) (x + 814)
