Problema Solution
The product of the page numbers on two facing pages of a book is 182. Find the page numbers.
Answer provided by our tutors
Let X be one page number so that second page is (x+1).
x*(x+1)=182.
x^2+x-182 =0.
By factorisation
x^2+14x-13x-182=0.
x(x+14)-13(x+14)+0.
x=13,-14. as page number can not be negative
one page number x=13.
second page number =14.
