The product of the page numbers on two facing pages of a book is 240. Find the page numbers.
The product of the page numbers on two facing pages of a book is 240. Find the page numbers
The esiest way to solve a problem like is to take the sqrt of 240=15.49. then you round one number up to 16 and round the other number down to 15. So, your numbers are 15 and 16. This is not a proper algebraic way of doing it, but you get your accurate answer anyway.
x^2+x-240=0
x^2+16x-15x-240=0
x(x+16)-15(x+16)=0
(x+16)(x-15)=0
x=16 OR 15
Answer---15 and 16
I hope
