A college library has five copies of a certain text on reserve. Two copies (1 and 2) are first printings, and the other three (3, 4, and 5) are second printings. A student examines these books in random order, stopping only when a second printing has been selected. (One possible outcome is 4, and another is 125.) List the sample space.

The starting equation is :

4x^2 - 2xy - 8x + y^2 + 2y = 5

I derivate as follow:

8x - 2y - 2xy' - 8 + 2yy' +2y' =0

y' ( -2x + 2y + 2 ) = -8x + 2y +8

y' = ( -8x + 2y +8 ) / ( -2x + 2y + 2 )

= ( y - 4x + 4 ) / ( y - x + 1 )

which I think is right, but my TI gives me this answer with ImpDif function :

( -4x + 4) / ( y + 1 )

Where is my mistake ????
