Here we answer the question: "What two numbers multiply to 636 and add up to 637?"
The answer to your question is:
1 and 636
Below we illustrate and prove that 1 and 636 multiply to 636 and add up to 637:
1 × 636 = 636
1 + 636 = 637
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 637x + 636 = 0
If so, the solution to factor the quadratic equation above is:
(x + 1 ) (x + 636)
To summarize, since 1 and 636 multiply to 636 and add up 637, you know that the following is true:
x2 + 637x + 636 = (x + 1 ) (x + 636)
