If we look at the page numbers, we'll notice that they are consecutive integers. So they follow the algebraic form , , , etc.
So if the product of two consecutive integers is 1056, then we have the equation
Distribute
Subtract 1,056 from both sides
Factor the left side (note: if you need help with factoring, check out this solver)
Now set each factor equal to zero:
or
or Now solve for x in each case
So our possible solutions are
or
However, since a negative page number is not possible, this means that the only solution is
Now to find the next page number, simply add 1 to 32 to get
So the two page numbers are 32 and 33
Check:
To check this answer, simply multiply the two numbers:
Works.
