Question 367099: A student opens a book with two facing pages. The product of the page numbers is 1056 find the page numbers.
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
let x = one of the facing pages.
let y = the other of the facing pages.
it's clear that y has to be equal to x + 1, so your 2 pages are therefore equal to:
x and (x+1)
the product of these 2 pages is equal to 1056
this means that:
x * (x+1) = 1056
simplify to get:
x^2 + x = 1056
subtract 1056 from both sides of this equation to get:
x^2 + x - 1056 a= 0
your factors for this quadratic equation are:
(x - 32) * (x + 33) = 0 because:
32*33 = 1056
33 - 32 = 1
you get:
x = 32 or x = -33
x can't be -33, so x = 32 is your answer.
you get:
x = 32
x + 1 = 33
page 32 faces page 33.
32 * 33 = 1056.
there's your answer.
