Here we answer the question: "What two numbers multiply to 691 and add up to 692?"
The answer to your question is:
1 and 691
Below we illustrate and prove that 1 and 691 multiply to 691 and add up to 692:
1 × 691 = 691
1 + 691 = 692
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 692x + 691 = 0
If so, the solution to factor the quadratic equation above is:
(x + 1 ) (x + 691)
To summarize, since 1 and 691 multiply to 691 and add up 692, you know that the following is true:
x2 + 692x + 691 = (x + 1 ) (x + 691)
