Question 161771: I am working on a problem in algebra. The question is: A student opens a literature book to two facing pages. The product of the page numbers is 812. Find the page numbers.
I would like to do this problem on my own, but I can't figure out the formula to do it. I have never taken algebra until now and it is driving me nuts. Any help would be appreciated.
Thanks.

here we go with the letter thing...
if x is the number on the 1st page, then the number on the 2nd page is x+1
the product is x^2+x __ this equals 812 __ x^2+x=812
you are looking for two factors of 812 that are one number different
__ the square root of 812 (on a calculator) is 28.5 (approx)
so 28 and 29 are good bets
